well, just like the comment in code says...
simply type /grouplist or select ut from popups, and view all #groups you have.
there's also info on #group status, option to enable/disable it, and file that contains selected #group.
this is utility, and it is done for scripters.
'cause I realy don't see how regular users can benefit from it
enoj \m/
Update
fixed error when clicking on list, and no text selected. It selected radio "Off".
now it won't do that anymore :]
