There is an existing Vanguard Dreadknight community over at
http://www.evilgamer.net/forums/. The folks of the EQ community were kind enough to set it up a few months ago. There are 5 board sections devoted to General stuff, Equipment, Quests, Class Balance, and Spells and Abilities. I am in the process making guides for the appropriate sections, and would love to see people get involved over there.
