No kidding. There are some cool features on there but they update every couple of months and have little news on Indy IV and everything else. Hopefully they'll update more as Indy IV draws closer (but I wouldn't count on it.)
Years ago I would've said Indyfan, but it died a slow and painful death. The official Indy site has improved a little since the release of the DVD's but it's no where near as good as TR.N and TIE. But... in the end, I voted for TheRaider.net.
