Does anyone know of there is a blacklist on TER?   I know the MNE grp seems to have black listed some of us. Apparently includes me.  I’d love to get back in their good graces, but can’t seem to get in touch at all. I have been able to arrange appointments with a few others, but even some of the indies are not responding.  

Hi Ro.
Are you asking  ...if TER members are blacklisted by MNE posters?  
Not as far as I can tell. They've often been grateful for review publicity and sometimes responded positively to criticism of reviewers.
2) and, once again, there are several groups on MNE, with similar but different approaches, as well as several independents. It's not monolithic.
3) it seems there's enough business to make them content to stick with known clients.  
4) Read the 4 Agreements. Actually don't; it's not that good. Agreement #2  "Don't take it personally" and #3 "Don't make assumptions."
I'll PM you with some ideas.

Do you know the exact amount of groups on MNE and which girls are a part of them?

You are either in their good graces or not but, there is more than one group and unless you are experienced with a group or groups, you won't know which providers are with each group.

Funny thing is that I had been a regular of the groups. I don’t know which provider belongs to which group, but I am pretty sure that I had seen someone from each of them over the past several years.  But suddenly, I get no response from any of them.  Or at least most. Every once in a while, I do get a response and occasionally can get an appointment.  I have even had a response and set up or tried to set up an appointment only to get a message that it was a mistake and the provider wasn’t really scheduled that day, or got sick.  Clearly something happened and I don’t seem welcome anymore, but not sure what.  I’d be happy to make amends and get back in their good graces.

I just thought about something as I cleaned out my Spam folder.  Is it possible that my emails are now being forwarded to the different groups spam folders for some reason?
