There's no real format yet, so I'm just throwing things out there. From what I saw when I was working on this in '08 there were several groups of skills. The rarest were the programmers. We do need everyone's help.

Right now the roles I can foresee (yes, I am Magi with the gift of Sight...):
  • SQL Admin & database designers
  • PHP coders -
  • Mapping experts - the program is linked in the Legacy of Kings forum section
  • Data Input - This is everyone who can't program, but wants to help.
  • DM/Idea Contribution - someone to help use with arbitrary decisions like do we use blind bids for RP contesting or allow the defending member to see aggressor's bids?
