Any of you guys on The Admin Zone?
They've got a few excellent resources there. They also have their own set of secluded Exchange forums. To get in, you have to join the Launch Team first, which will give you access to The Exchanges later. What first has to happen though is you make ten posts in two forums from the Launch Team. You then will have access to the exchange. The Launch Team forums change every month. Those who make fifty posts on the team can apply to get on the next set of Launch Team forums. The last time I got on the Launch Team, I basically got 300-500 free posts. I'll be honest for a bit, their post exchanges are more mature and are of better quality than Forum Promotion's posts.
