13 This code has not been tested exhaustively. Use at your own risk.
14 This code opens the userdict.pickle, and if it gets corrupted, you have a
15 problem. You have been warned.
16 The multiple column support has not been tested, but is assumed to be
17 working.

20 This macro displays a list of currently known users.
21
22 Usage:

24 [[UserList(column1, column2, ...)]]
25
26 Demo. Try pasting the above examples into a MoinMoin sandbox page.
