I did that and that one is not free, it has a 30 day trial...
Well, none of you ever organized a tournament using this kind of software?
FWIW I use that particular one (The Tournament Director) regularly when I deal live and if you're going to use it more than a few times it's worth the money - it's really easy to use,
very customisable and it's probably got more features than you'll ever need to use.
And if you only need it the once, just use the 30-day trial.
The alternatives are just using a normal wall clock or your watch or something and calling the blinds out... I dunno, exactly what kind of stuff are you looking to "manage"?
