as a point of personal interest and curio, could someone explain the differences between 3.0 and 3.5? i joined the game late directly from 2e and never really realized there was a difference until a few years ago.
The SRD to use (IMO) is here:
The Hypertext d20 SRD (v3.5 d20 System Reference Document) :: d20srd.org
