Once you assign Limewire a folder, it owns it completely and forever: there is no way to remove sharing without Limewire directly trashing the file. This, I should add, is a very un-Mac way of doing things. The safest method is to use aliases. I move various aliases in and out of the shared file. Plus, if for some reason I don't remember and try to remove file-sharing, all I have lost is a bunch of aliases, not the real files. I'm sure there are people out there who unwittingly zapped their iTunes folder, thinking they could simply remove sharing as in Aimster, etc.
