Brainstorm other ways to get funding. Group too large. Split the group up, either by geography, interests, or meeting time. This will keep meetings from getting too cumbersome. If your group is doing too much at once, you may wish to split the group along the lines of the areas of interest, instead of doing many things poorly.
Group changes from founding basis.
Often, as new people join a group, it begins to change from its original purpose or its politics may be altered or diluted. To avoid the latter, the group should be founded on an explicit basis. Coalitions are more susceptible to manipulation than groups with clearly identified politics. Go to the Anarchy for Anybody Homepage.
