Maybe there could be a meeting first, for all who are interested to be in the commitee.
At the meeting we can appoint key members, like chairperson, tresurer, secretary...blah..blah...sorry I sound so formal.
(I must say that the key appointment holders are very important, so must choose carefully, like we would really use good leaders, just like our own govt are)
Then we can draw a list of the expertise, and particulars (also time commitment) of all the individuals.
Then with that list we can secregate different teams and field of expertise.
So when a project is at hand, each team will be task to gather all the resources. Hope we can have a vibrant and sucessful community.
