I am certainly a new provider , I have been using TER white list and pr411 to screen ,  is so easy that way . But when there are new clients who  are newbies and dont't have refferences , how can I screen ?
Suggestions please!!!

Screening is like a science, you need to know the facts in order to make an informed decision and while having all the resources available (references, handles, etc) may help you, if you have to ask it may be in your best interest to "shadow another provider" when she screens her new clients. Until you get more experience, I would avoid seeing newbies, they are harder to check, or you can also suggest that they sign up for P411 date-check or RS2k and acquire references so you don't take all the unnecessary risk. Keep in mind that while P411 and TER handles are great, there is way more info you need to look into (blacklists, references etc.). Nevertheless, always follow your intuition.. Personally it has served me well so far..
Be safe!

Many providers are very secretive about their screening methods.  What you told her is very valuable information, and I hope she takes it to heart.  Screening is a very necessary process for you gals out there.

Be happy to help you via PM or email because screening is a bitch when you first get started. Many guys will try and manipulate you, so give me 10 min. of your time, and they will know you talked to London bwahahaa.

Oh great...another provider using LRs pre-certification process.     Are you up to peepster, or shrimp even?

I can vouch for this statement.
