Review/ad/discussion boards:

ASPD (Adult Service Provider Discussions) 
(I’m a long-time member, and a former moderator from several years ago, although I don’t post much anymore.  It was hacked in early February; back up a couple of months later but continues to experience occasional glitches and down time.  There is a “back-up” board allowing members to congregate, exchange information, etc. — limited access, though.)

ECCIE (Escort Client Community Information Exchange)
(Fairly new, started about the time of the ASPD hack/crash in February 2009, but has been growing well.  I’m a member, mostly lurking for now)

The Erotic Review
(I’m a member, although mostly just a lurker; more national in scope and not well established in Texas)

Midnight Live
(If not already a member, you’ll have to get an invitation through their system or else supply references.  See here.  I’m a member there, but don’t participate much.)

HornDogs 
(I’m a member there, although mostly just a lurker; it’s more focused on Houston rather than Dallas)

The Other Board
(I’m a member, but almost never visit.  This was primarily a Colorado-based board, but is now starting to branch out to Texas.)

AHC (After Hours Central) – [members only]
(I was a member at one time, but left awhile back; it’s not a great fit for me, but might be for you)

Preferred411  [**]
(I’m a member. It was primarily an advertising/screening/client verification site, see below, but now — in part due to ASPD being down — also has mini-reviews and discussion boards)
