Mrafrohead: You should NEVER delete files belonging to others users on a system, even if you are the administrator, UNLESS the files in question are in breach of any 'rules' in which the users have to abide to use the system. Furthermore, you should have a little common curtesy as the administrator, what is theirs is NOT yours, you wouldnt (i hope) read their personal diary so you should not be nosey and looking/reading in their personal documents either. But whatever, this is all besides the point...
My views are that mirc should NOT (by default) remove this data on uninstall, however i DO believe that the uninstaller should provide options such as 'remove data files for current user', 'remove data files for all users (administrator)', 'do not remove any data files (default)', 'remove registry entries' and so on.
