Before I send the Welcome Mail to an extranet user, I want to be able to change the content in some cases.

It is confusing that a space admin, can manage permissions via "Extranet Users" and still has the option to user the default Confluence space permissions functionality. This also leads to configuration errors, when assigning external users via the Confluence permissions interface. This interface should not be available for normal space admins, but it should be possible to limit access to specific users (e.g. members of specific groups).

Hello, it would be great if not only the username field but also the email address field would be a unique field. The background is that for some users there are multiple accounts, although this is not needed.

As an administrator I want to change the template of the Welcome Mail.

Our experience of the last years has shown that many external users have been created multiple times (sometimes from different space owners). Therefore we believe that it would be helpful if the sys admin had the option to specify that the username must be an email address (checkbox), or alternatively via a string field in which you can enter a username validation reggex string for field validation. Another idea is, to search over all existing users (Full Name Field, "Forename Lastname") int he "create user" dialog and then "warn" the space admin if a user with the same name already exists.

Passwords should have a certain complexity to protect them against brute force attacks. For this reason, it would make sense to set up a password policy setting. So far there are no options in this regard and therefore it is possible to set e.g.: 1 as password.

As an administrator I want to check which extranet spaces an extranet user has been assigned to, so I can be sure that everything is configured as it should be.

Possibility re-direct "extranet-user-group" to one certain space instead of Intranet front page. I know this is part of the Theme add-on but unfortunately it requires linchpin manager.

Space administrators should have the ability to de-activate users directly from the space. This helps keep the system clean and the user license down

Based on the space category, I want to have different Welcome Mail templates, so the email fits to our company's use cases.
