It would be perfect to see what you've got so far. Then, I think you'll get many more suggestions. Coppermine out of the box is pretty bland (since anybody else could do it). But with some mods, I'm sure you can make it a pretty cool place to post!
Yea.. but I see that as cheating. When you install scripts, you can learn how they work and if there was ever a problem, you would be able to figure it out easier. With Fantastico... if you ever want to install something, it may not let you.. and it's also a hassle with uninstalling because it leaves the files that you create in there...
Fantastico... cPanel.. Modernbill.. If only you knew what kind of pain that brings to the hearts of server admins everywhere. Nice once you get it setup, but maintenance and trouble-shooting is a nightmare.
