Some people have tossed out ideas here and there in different threads, thought it might be a good idea to put them in one thread and then hit the devs with our ideas. Lots have people have mention...
I definitely agree with everything said here. This would really help medium level guilds organize much better.
EDIT: Well, really every guild. I just said medium level because they normally still want to do well but don't have the time or resources to coordinate more casual players (myself included).
