Registrations have been enabled again, requiring manual administrator approval of the accounts. We checked to ensure that it is also the case for social network-based registrations as well and if that's not the case, then social login will be disabled until the first. People can now sign up fine, but we will not approve any new account until January 1st. An e-mail will be automatically sent when they are approved.
Good to hear we got that sorted out. :)
Well, we have yet to see it tested. :P
I actually got an idea, though: I'll try signing up via CodeWalrus Twitter account. I just don't want to risk locking myself up from using Reddit as login medium in the future.
EDIT: Confirmed to work. We should be safe now :P
Cool to hear. I hope that we can drive the site to open registrations. :)
