Looking to hear everyone's thoughts on providers who either never answer any communication method or are just really bad about it. If you are discreet and respectful but continue to not hear back, at what point do you all move on even if she is someone you are extremely dead set on seeing?

Don't take it personal, there is a big ocean out there with a lot of beautiful fish ranging from whale sharks to damsel fish; move on. It sounds to me that you are getting too vested in one lady. It could be you are pushing too hard and turning her off. My advice, find someone else with similar assets.  

Some guys hate it when a girl does not answer or when she takes forever to answer. Others simply move on to another or the next.  

Many providers don't want to deal with Newbies. When you get to 10 reviews, you'll get a better response rate.

Well despite my only 1 review, I have the 2-3 references that providers ask for, but my TER track record hasn't even come up yet. My current frustration is with a few providers who at once time responded to me, and now will not. I guess at some point I have to give up my persistence?

Long before I ever wrote a review I was seeing top notch ladies.  Lots of guys don't write reviews or even   have an account on a verification site.

I feel so lucky to have your guidance, and in the future, I will try to be a little less obtuse. Lol

It was a lame response and you knew better.  

I followed all the requirements, was polite, and have very legitimate references

just one more reason i use P411..you request an appointment and they usually will get back to you within 48 hours..if not they are usually not logged in..P411 will give you their last log in time..

want appointments not hobbyists looking for a pen pal.

Unfortunately this isn't the case either.

Knows I NEVER use my TER handle to make appointment, so it was tongue in cheek humor. As you say, my 100+ reviews don't mean shit for booking appointments for me either.  Don't take everything so seriously and you'll have more fun here.  If it will make the world right for you, I will give him a legit response.

Apparently these women have a different opinion and have ghosted on you for "some reason"

Julia's analysis.  99% of time wasters don't think they are time-wasters.  Setting an appointment in advance and reconfirming it the day before only takes three emails.  More than that is an encroachment on her time.  For providers, time is money, and they don't want a bunch of back and forth communication unless they're compensated.  

Thanks for the good advice. I don't mean to complain, seeing as I've had several successful communications with several other providers, but these 3 who I really would like to meet aren't working out in the same way, so it's a tad frustrating. I will learn from this and give them some space for now and try again another time while I move on to other providers.

A newbie asking how to track provider's specials, sounds like you might be looking to negotiate their donation.
Or maybe not.  

I agree, it can be a few things. I get so overwhelmed with inquiries I really can't get back to a lot of people... so the ones that are polite, follow my protocol and have an actual appointment date get my attention first. The others I ask to just keep checking with me as I'm just so busy. I spend more time answering inquiries than anything else, it's  crazy.

#1.  Did you only say you had references and were ready to book, or... did you GIVE her the references and GIVE her one or more days/times you were available?  
#2.  Two weeks is within a "week or so" timeframe.  Be more patient.  Maybe recovery took longer than she expected.  
#3.  When someone says she's out of town, don't expect any response until she's back in town.

LOL ... thanks for saving me the time. We can hypothesize on 1, 2 and 3, but none of us really know what transpired between you all.

even if you prefer to screen for yourself. He/she can help you filter you mail and make requests for more verification info, etc.  

Bottom line, her pussy, her rules. If she has a gut instinct to not contact you, so be it.  

now we learn you're overweight, obtuse one ...  
TMI ...  lol

If you show too much interest in her before she's interested in you she won't find you interesting enough to warrant her time.
  You are on the right path when you quickly move on.
  There is no shame in coming back at a much later date, minimum six month space.  
  If  you only have six months to live, it's OK to give her a shout out in four months.
   
Always remember the rule that applies to EVERYONE EXCEPT our mothers.
  Regardless how awesomely appealing and important  we believe we are, there is always someone out there that can easily replace us, quite often a better replacement.  
 
 I have exceeded my expectations many times over in the civilian world by not giving a damn enough to be persistent.

Depends.  If it's a new provider I haven't seen before, then 2 or 3 days is not unusual considering the time they'll need to check my references and other screening info.  If I don't hear back after that, I'll send another email to follow up.  If there's still no response then I move on.  I don't have this issue with providers I've seen before, they usually respond back within a few hours.

Can mean "I'm on vacation with my husband and children, please stop emailing me till I get back"
"I'm on a paid date in Dubai with an intense client who is looking over my shoulder at every turn"  
"I'm burned out and need a break from sharing myself with people who are new to me"
" I just dusted a stalker and this is starting to feel like that"
"I'm on a trip to Iceland or Burning Man and the access to internet is sketchy at best"
Take a deep breath. Relax.

Dated April 21st.  I asked a provider in Seattle if she'd be interested in seeing me April 30th, was willing to provide all her info requested.  She replied today, May 9th.

Well that's a bummer. Any idea why?
