I found looking over the UIFILE.txt code, and modifying things here and there turned out better, as i could do alot more things that cant be done in LogonStudio.
I left comments all over the code so that its easy to modify things and work out what lines do what..
Im gonna get a tutorial done real soon, cause theres alot ive worked out to do that logon studio doesnt/cant do, and even some things noone else has worked out (like displaying the welcome text).
