Darn those limes.
SoT: Jan 4th, 2011 - Fairly recent and I'll list some of the other new stuff here:
Reliability condensed a lot of Gym Leader information and such. There's been discussion about the new site design, which I'd like your input on.
We're still working on previous gen Pokedex entries. A lot of the discussion has been stalled so if you want to get involved/vote then that'd be cool.
If you can do art, sprites, whatever then you can post in the relevant forums/threads and ask what needs doing. Otherwise just looking at threads around here and putting in your two cents is a great help.
