There's a wiki up for Elemental up at http://elementalwarofmagic.wikidot.com/. It has been running since Beta 1, though it has been a little neglected as of late. So if you want some information, stop by and see if what you are interested is on there. However better yet, if you'd like to contribute, stop by and update it with some new information. There's a lot to document for such an epic game so more community participation helps.
