I think having three active mods would be an ideal situation. At any given time, one person could be tied up with school, work, family stuff...etc. That way there would always be two people on hand to run challenges, do day to day stuff, etc. It also would help keep things fresh creatively, I think, if we were able to bounce ideas and manage tasks as a group. Also presents an individual from getting overloaded.

What do you think?

And while it's not a rarepair, the Potterverse did have the Trio...plus we'd have peskywhistpaw as our Dumbledore!
