Wekan: Bug: Unable to add an existing user to a board [v0.16]

[NoodleBB]

Setup

There are different users on the host. Each user has it's own boards.
Alice (Admin user) want to invite Bob (non-Admin-user) to one of her boards.

Problem

There's no way to add an existing user as a member to someoneelses board. In the Admin Menu, you can invite only new users for registration. When you try it with an existing user, it fails.

Error

When you try to invite an existing user via Admin Menu Registration to a board, you'll get an Error in the log: Error: Email must be unique [invitation-generated-fail].

Conclusion

It seems you can't invite somebody, that is registered on the same host. 😕

@NoodleBB You're able to add a registered member to a board by going into the board itself and clicking the + sign in the upper right corner and then simply typing their username.

I think invitation by the admin panel is for inviting new members into a closed system only. Once they're in you can use the above method to add them to specific boards.

You're right. Thanks you.
I would await that function in the board menu. But not in this "_right-side-slide-popup-log_".
