Some users don't have the invite text-field on 2.1
So using 2.1 on my forum, with registration set to invite some users seem to have the text-field to enter an e-mail, while others do not. I have checked their member status and looked at the users but have found no difference. So far I have been unable to find a pattern between the users that have the field and those that don't.
Does anyone here have any ideas? Maybe even fixed the issue themselves?!
