the only purpose of the minilogin I beleive it to stay mini! (1 login) It is there to test a local server easily.

As a plus though it does seem to work pretty good and if it isn't, it is usually a simply type-o on your part. There is alot of info about it, in its README, and in the win32forum (yeah, some do ask about it there
