Giving other members the permission to edit

This feature was something I wanted most for forums. Contests and events often has more than one host or perhaps helpers to help the orgininal creator of the idea, but things that include entries or mentioning mebers, well, helpers can't seem to help the creator with that, when that seems to be the most tedious/difficult job to handle. A good example can be the community event calendar. Or something like it. The creator can add certain members, giving them the ability to edit so they can as well add new events instead of a single person adding all the new stuff on his/her own. I'm not demanding for this feature, I just got this idea after I realized I didn't have enough time to add all the entries for my contest and I appeared to have 2 more judges that were available for the job; thought it could come in handy
