is it a guild meeting, or a sit and sew?
If my sit and sew started organizing stuff I'd probably run away. But some folk like to be organized into doing stuff,
I don't have any idea how guild donation tables are organized, but our little sit and sew already has 7 bins, and the person that started it said last week she was through shleping them back and fourh. Maybe an occassional bring and take, but everyone bring their stuff in a bin and then take their bin back home?
I would certainly ask the group what their hopes and expectations are.
