Links
Here are some recommended links, more will be added as needed!
The official Dragon Ball website!
Viz Media, the official North American distributor of Dragon Ball...and many other series!
Kanzenshuu is THE premier Dragon Ball site! It's a very old fansite with roots that are even older, but there is no greater wealth of Dragon Ball information elsewhere. There's news, a massive translation archive, forums, an EXTREMELY detailed wiki being tempered to perfection...the list goes on. I can't possibly do them justice with just my gushing alone, so go check them out!
