OK, some quick links for UO.

The official UO Homepage. Well, if you have no clue what UO is, or you're looking for stats on guilds, this is a good place, otherwise, um, go to stratics.

UO Stratics. Detailed info on skills and ingame items.

UO Powergamer Site~~For those of you that want to hit high skill levels with the least amount of pain, this spoiler site's for you~!! Although, I, myself, use UOA (a legal uo add-on), this site mentions a couple of not-so-legal add-ons.

UO Assist~~FINALLY an OSI-approved LEGAL 3rd party program for UO that doesn't suck~!!

UO Map~~ever wonder just wtf you're at? Just load up this APPROVED UO add-on and wonder no more.

B0N3D00D and pLaTeDeWd~~Two HILARIOUS PKers... I LOVE these guys~!!

Musashi ~~ALMOST as hilarious as B0N3 and pLaTe
