Sometimes it seems like they don't want help or input, but the problem is (ime) that people are plenty willing to make suggestions, and much less willing to implement them. Our pack stagnated for awhile, because no one was willing to take an actual position. This year I sort of gave up my den leader position, in name anyway, to become chair. We had to have a chair and no one else would take it. Our chair had to move up to pack master. Now, how crazy is it that big positions that should, imo, have all the pack's adults taking part in choosing the right person, are being sloughed off onto the people that are willing to take them in order to keep the pack going?!?
So far I have "nominated," that is to say signed up and helped them fill out their paper work, people for lots of the seats that were left "open" (iow, in the laps of the three adults that were trying to do ev.er.y.thing.). Here, it's almost like you have to force people to just sign the paper already!
Oh, and I'm barraged with all sorts of helpful suggestions and (as usual) expected to run with them while I juggle everything else, including my den.
All that to say, attending the leader and committee meetings while offering to do the things you think need to be done, will probably mean you'll be given plenty of permission to do them. If you wanted to take over planning the pack meetings, for instance, the p master and c chair will most likely be glad to dump the lot in your lap ;)
