I don't really sell a forum posting service anymore, I will usually come and make a few posts on a forum if someone asks.. We used to do a forum posting trade.. there's lotsa cool ideas.
Some people have just offered .50 or so per post here on these forums for people with some time to come post .. truckin used to do some of those I believe.
POMF (mentioned above) generally gets really really great reviews, or really really bad ones. I worked there for awhile.. a few years ago :P
They're the best though if u are going to hire posters, because they received huge amounts of traffic from CAP awhile back and hired a buncha people that have actually played a hand or two
There's also xxwww.forumboost.com I believe that's the url anyway, theyre not to bad. U can also advertise in DP, lots of people do.
The moderation service I offer is more occasional posting, and daily spam removal, conversation starting etc.. we talk.. but we don't talk to ourselves
.. if that makes sense ..
BTW... Thnx Bah! for thinking of me
