My site is http://wranglertjforum.com It's only been up for 4-5 months, but I'm already at 610 members and it grows by at least a few members every day. The forum is pretty active now and I'm surprising myself with how quickly it's growing (610 members in 4-5 months isn't that bad, right?). Anyways, I've gotten two potential vendors / sponsors so far who were inquiring about how much it would cost to get their own vendor sub-forum as well as possibly a potential banner. The thing is, I haven't even thought about this until recently since sponsors wasn't even on my radar until the forum was even bigger than it is now. So, my question to you guys is what are you charging for sponsors / vendors to be a part of your forum and advertise? My plan was to give a sponsor a dedicated sub-forum where they can advertise their products, but also allow them to add links in their signature (to their products or site), as well as let them promote products to members via responses to threads. I just don't have any idea what would be a reasonable amount to charge per month.
