A userlist module similar to the Stats module - which can be customised and placed in any module position totally separated from the forum ie. with no forum menu tabs at the top. Sometimes it's necessary to make a memberlist viewable to the public, but without certain details ie. profile links, date registered etc. These could be checked on/off. Other options could also include the ability to add other details such as rank etc. and show only users of a particular rank (multi-selected from a drop down inc. ALL, and whatever other ranks ie. possible to select more than one rank?) + change basic presentation css styles so that it fits in with your template style.. backgrounds, text, borders etc.
