There was a slight error of judgement made by one of the deveopment members to prune inactive users (just after a forum transfer - not a good idea) that killed 80% of our users.
I have been working out a way to get them back and think I have it solved.
Those that have re-signed up with the same email address and password as their old account will find that their registration date and post count has been reset to what i was in that previous forum.
That that have NOT re-registered have been re-registered.
Those that HAVE re-registered BUT with a different email address and/or password please let me know and I'll manualy fix up your accounts.
Sorry for the hassles.
OD.
