You should obfuscate those emails so bots don't pick 'em up. Also, the SW Central link isn't working; it should be:
http://www.tbns.net/sw-central/index2.html
You can see that pretty much all the sites have the same stuff. Walkthroughs, secrets, cheats, level/monster/item/game descriptions, shareware...
TCs and maps and anything unique are really the only things that could be of use; maybe some DETAILS on how to play the original in 3DFX mode (although that's kind of pointless now, too). Is there anything really NEEDED out there?
Probably the best bet is just to make a new thread in this forum if you have anything in particular to offer.
