1) If you're a member that has Twitter, use it. Make it a point to get on there every other day, and tweet about how awesome this place is...about how you've experienced other MMA forums and none compare to The MMA Community. About how people should sign up and see what we're all about. I try to tweet as much as I possibly can, but I also work a full time job, go to school, etc. So to have our members promote us on Twitter, where I can retweet it, would be a huge help.
2) We have a pretty consistent average of 20-50 guests online at any time throughout the day. When I tweet articles out, that # can be 80-100. We need those people to sign up & participate in discussion. It takes 30 seconds. We have a very welcoming group of members. Guests/Lurkers dont get access to the incredible features we have here. It makes no sense to me, to not sign up. If they did, it would help us immensely.
3) We had 200 people sign up here in the first two weeks after we launched. The problem is, 80% of them gave up on us after a week and went back to the other site. You can see who they are and the last time they logged on, under the member list. Those folks likely have no idea how awesome this new software is, because they were long gone before we ever changed over to it.
4) Tell anyone and everyone you know about us, and tell them to sign up & participate in discussion. Word of mouth is big.
5) Participate in the Q&A's. I book these things with great people that are willing to take time out of their busy schedules, to spend a couple hours interacting on a forum that is only 4 months old...and a lot of people here won't even take 30 seconds to post one question for them. It's hard to promote that Q&A on Twitter (when it's done), when all of the questions are by the same 6-8-10 people. And it's hard to convince other fighters & MMA personalities to do one, when they see the lack of participation.
