Much of the work done at FREE GEEK is done by self-selecting groups of people who are interested in the particular job done by that group. Some, like the ASSes, meet on a very regular schedule, some meet monthly, and some never meet as a group but still get stuff done. It's amazing.
Policy and procedures for the areas of FREE GEEK that fall under the purview of each of these groups is left up to the group in question, unless it will influence more than one working group, it might conflict with FREE GEEK's mission, or it might be subject to controversy or conflict. Then it goes to the Council.
The staff standing subcommittees are similar, but have more to do with coordination of all these groups.
