Cake/Gib to hand over the database with user's info in it would rais all sorts of privacy/legal issues. I have developed a few forum systems in the past. If I could find the time, I might set something up to crawl the forums and harvest all the publicly available data i.e. threads, posts user, names etc. and make it searchable but no personal user data/accounts. You would have to re-register to the system I built to interact with that. However, it's probably a pointless exercise anyway as I suspect, whether we admit it or not, we will all gradually lose interest in Sonor and the forum will gradually become a graveyard. Or the forum may stay here for ages.
There is WayBackMachine, but all the forum posts won't be on there.
