I think this is a good idea as it'll be nice to have information pertinent to us in this part of this world all in one forum.

Here's one from NWA:

Aside from this, here's an old NWA campaign that I learned from a FTer early this year but still ongoing. I'm sure most of you guys know this already, but it would be nice for any newcomers to know as well.
