For what I know... you can't (somebody correct me if I'm wrong).
I realized USay is using a .dll developed by the author(s) and a function called "Suggest Font" or something like that. Maybe they're trying to use their own method.
You could try and download USay script and see if it works x u.
BTW the script has been updated... It would be nice if you guys could check it out... sometimes it's happened to me that when I use the /cloneT command when I logg out and back in, I find the nickname to be the one I used /cloneT on (even though, of course, the nickname switched back to mine).
And yes. Keep up the good work Menthix
(2 thumbs up).
