I try to find my place in a group as the organizer who just looks to make sure things are done. I schedule the group meetings, right out lists of what needs to be done, keep a time line and contact, document resources and usually compile the bibliography.

I try hard to keep things equal so I don't deligate tasks I let everyone decide what it is they want to do.

Sometimes in groups I'm not the organizer, but instead I'll do all the preliminary research and present my ideas for a hypothesis that is discussed among the group. And in this case I usually also act as final Editor.
