I note now that invited users receive an email after accepting an invitation which invites them to choose a password. In the same email could they be invited to choose a user name?
At the moment with the invitation system one needs to be careful because people can be invited and immediately post a message without realising that there user name will often be their full name, which they might not want to be public. There is also an issue where people’s names will appear on members lists which often are public. People accepting invitations should know this will happen.
My preference to get around these issues would be to have the default selection of user names to be randomly generated, rather than have default to the first part of the invitee’s email address. Would it be possible to at least have this as an option in the admin settings?
