sessions are no big deal - search the list archive for stuff like 'form token'
until you find one of the many explainations of how to tackle this issue using
a 'one time' token concept (find the posts by Richard Lynch - they are the most
complete/abundant/explicit AFAICR) - the solution does use sessions, but like I
said thats not a big deal at all. :-)
