On Emerald: Not until there's a second GM, at least, as I've stated previously. I'd prefer no outright, mainly because I think the symmetry between teams as it stands is fine as it is. The two teams have 'niches' that they fill and villains they specifically target: Who would Emerald be, lacking the brute-force of Ruby or the stealth of Sapphire? Who would Emerald Target, lacking either Magma or Aqua to fight against?

I think the need for Emerald will die down in your eyes once a new GM comes and picks up the slack for you in one of the threads, Savvy?

On the story-writing thing: That sounds fine by me. :D
