Creating skins is an important aspect of any script but I don't think that's really the priority. I think fixing the php codebase (depreciated functions etc.) is more what's joeroberts is after at this moment in time.
I did a few fixes earlier this week but the SMF 2.0 release has kinda sapped all my time in the last few days as I need to update xbtit for it.
FWIW I really like the eVo_blue theme joeroberts.
