Well i would appreciate it, if i could control the permissions, especially for the users which are not logged in (especially
view).

for Example.

Some Wikisites in the Project might be only for the developers. Right now, all useres have read write access to the
wiki, even ones which are not logged in.
BTW i would prefer a wiki where authors have to register or use a guest account.

Also some documents might be for internal use only.

Cause of this it is important, to get more control for this areas.
