I swore this was a standard feature on the 2.0.x, but nope... I would really like to be able to make the forum an invitation only -forum, but so that the members could invite the people they wish to invite without me having to manually create every new user as it may come down to. I have a workaround using the anti-spam verification questions, but it is very clunky in comparison to what I want to do. (I may need to change the password on the fly when the registration password gets in the wrong hands or I just want to change it, while someone is just trying to register with a code given to them by their friend... :/ I'd much appreciate invite codes to be individually set, preferably by the member who invites people, so I can pinpoint who has a poor judgement and remove their invite rights!)
This is seriously the only thing I don't understand why it is not there yet, ideas as I may have!
I like to create very complex forums, and this is the only really needed, obvious thing I can't find either a mod or a core function, but as it is something that I find a security issue, I'd really prefer to be in the core.
