Um why don't they just back the database up. It isn't that hard to do.
you type "mysqldump .sql"
This assumes it is PHP nuke using a mysql DB or sonething similar. I am suprised that the hosting company doesn't do this for amiga.org as normal practice.
Perhapps they could do that once a month rather than emailing details all the time. And then people don't need to re-rgister. restoring takes about 15 seconds as apposed to the amount of time would take to re-register every one's account.
