This is going to be a pain to those who registered with fake emails or have multiple accounts and then need to create new ones just for this .
You are right. There are fair amount of users who use throaway emails.
Isn't there a better solution?
Slickage doesn't have access to password and thus, they can't migrate it to new forum software. So they will send emails. However, like theymos told, we might be able to login with old password.
What about getting a PM here with a link to synch/claim your account on the new forum? I think that would be far easier if it could be implemented easy on the admin's end.
It is better IMHO. I didn't think about this. I am pretty sure a bunch of bots will come with fake PMs. Any way to solve this?
