I'm for putting the full auto stuff into the rifle/pistol/shotgun/etc. forums, respectively. Not only does this help for normalization, but frankly, at TFL very few people ever read the Full Auto forum, if the post count there is any indication.
Besides, there were plenty of discussions about the G36, M16, FAL, AK-47, and other select fire rifles in the TFL rifle forum anyway.
As for short barreled shotguns, why not integrate them into the regular shotgun forum? What's the difference between an NFA shotgun and a regular one? Usually, it's 4-6" of barrel length. The misguided laws in this country make a big deal of that, but in reality, it's just 4-6" of steel tube.
Definately seprate legal and political from General Discussion. People usually get along in GD. People usually argue in L&P. Better to seperate the two for civility sake.
I like the idea of keeping my user name. Though I had a different user name for the first two weeks of my TFL membership, I've grown accustomed to being the Nightcrawler and have even changed my hotmail address to such.
As for my post count...aw, hell, I didn't manage to crack 3K anyway. If we have to start from scratch, that's no biggie.
I certainly wouldn't mind a few advertisements, as long as they're not annoying, don't have sound (like some ad banners do nowadays) and don't have any popups (Lord knows I get enough of them, thanks to NMU's special operating package on this laptop).
Also, a comprehensive links page would be nice, to all the firearms manufacturers you can find websites for. Members could submit websites as they run across them and the link could be added. If the link turns up dead, the moderators could take it down at the next update. It wouldn't have to update often (once a month or so, maybe?).
I'd suggest avoiding becoming too graphics intensive. Vbulliten allows things like avatars, etc, but for members on dialup those things are just really annoying.
