Yes the database is the key i suppose, I would love to see this happen so i am willing to lend a hand to administrating the db.
The most thorough and very excellent database of amiga demoscene information i know of is:
http://janeway.exotica.org.uk/search.php
I wonder if we could scrape data from there, or i could even ask them if we could get backend access to their db, i chat to them on irc too so wouldnt be hard to ask.
Im just thinking aloud im not necescarily saying my idea is the best one, i welcome all and more input
Also thank you for the fast reply FrodeSolheim, its nice to know you devs listen, which is what makes you and your project so special
