How much do they cost? And is it possible to upgrade from TSE v2.5 
(Single User) to a TSE v3.0 (Multi User) (whenever it may be released)?

Hmm, if my days gonna count 48 hours, I'll take a look at it.... :-) But 
thanks for the tip!

Will there be in the future a complete manual? Maybe the next time you 
could add is an extra, so that you can order a copy of TSE w or w/o a 
manual?
Thanks for your time,
