Do not allow new user editing until he/she participates in the forum
In my opinion new users should not be allowed to edit anything until he/she creates an account on the forum, as a mean for other editors/AM/CM's to contact back the user in case the editing is being done improperly and/or is destroying previous work.
As it is today there is no way to reach those users, unless one is lucky and find it out on the client (and he's not private), and would turn AM's into "lock everything" mode with the frustration of having the work destroyed by a newby.

Just got reminded that the forum account is automatically created, so it is possible to DM the user in question. Only if he/she then doesn't answer it, then support should be contacted. Please unvote and someone delete this item.
