Thank you both, must approve users is it. I had no idea that it would also prevent the adding of existing users to a Private Message. Surely this is unintended - I would have thought that we would only want to prevent the addition of email addresses to Private Messages rather than blocking all additions.
I was kind of hoping that this commit would resolve this problem, but it instead fixes another one.
At present we have to choose between:
- Allowing people to sign up (subject to approval) and having no user additions to Private Messages
or - Becoming invite-only and having a workaround to allow casual signups
@awesomerobot, would you consider asking for this to be addressed? Is this a bug report or a feature request?
