how do i get the 411 on agencies parties and other social gatherings with providers

and who knows you. Basically time and patronage are what counts. Hang around for a year or two and see 40 or 50 gals (post some reviews)and you'll begin to get the 411 your looking for....

I have been with TER Discussion Board for a little over a year now.  I have viewed TER for a few months more than that.
You will not have to be here for a year or two and invest $10,000 or more to find out when social gatherings are taking place where you can meet others of the Community.  You do not have to post reviews, either.
The reputable, established agencies such as Club TLC, Elite Introductions (formerly Scottsdale's Elite), etc., will keep you informed if you register with their mailing lists or visit with one of the ladies that they represent.  And, of course, this discussion board is a great source of information when one of these events is taking place.
Keep watching and enjoy yourself.
