Hi all!
A couple of us have been working on a wiki in the background, which also features modding guides and resources.
http://bfga2.wikidot.com/start

Currently released Mods:
http://bfga2.wikidot.com/wiki:modding
Modding Guides/Resources:
http://bfga2.wikidot.com/wiki:modding-guides

If you'd like to see a tutorial/guide on something please post here and we'll add it : )
Do note that the wiki is only half done at this stage, additional contributors are more than welcome.
