I have a few ideas for ya based on some previous site administration/moderation I have done... but the site is really great! I like the community so far as well. vBulletin is far and way the best forum software out there but not cheap.
1. Emoticon Pack. I can probably get a huge emoticon pack we have on another forum for you if you like. Similar stuff like you have.
2. Site Supporters. I am sure you have considered the vB addon on for that, but I think you should do it. Like I said, this software is not cheap, not to mention hosting or electricity if you run your own servers as I do, and we could pitch in on that. We used three different levels on our site and it seemed to work well.
3. Classifieds... I have a couple rules I would like to run by you.
4. Maybe a couple other forum topics here and there... but that stuff comes with membership.
Not being picky... I just got here!!!! And I really like the site. Just suggestions since you asked.
Everything looks fine to me. Since this is a Texas site, you can't expect the traffic you see on something like AR15, or Glocktalk. But there are lots of Texans that like to talk guns, and the word will get around. Keep profanity out, and don't be afraid to close a thread if it gets out of hand. Although I've not seen that, as the forum grows, eventually it will happen. Turst me, most people appreciate a mod that can take control when need be. A lot of folks just leave places when things get out of hand.
We currently have a crisis due to the impending election, this alone could even end the chat board and or publically shooting firearms and etc. Just for now let's focus on the possibility that very soon we may not be able to do what we enjoy most.
