Whatever we call it, "brainstorming," "proposed charter project," or whatever, there is no harm in collecting ideas and discussing them. If anyone from Playmobil even reads what goes on here at Playmofriends (I hope someone does, but who knows?) these are just ideas, thoughts, wishes, desires, etc. I acknowledge the potential for harm to the collectors club if we were bombarding them with these ideas, but we are not. This is an area for discussion among the members of the fan community so all topics about Playmobil should be encouraged.
As to cachalote's proposed structure, personally I like it, but I think that trying to enforce something like that in a loosely organized online community is hopeless. We can end up spending more time working out the structure and keeping people in line with it than we actually spend on generating ideas.
