It took me quite a while to sign up a new test user on my forum yesterday because I forgot to enter the invite code.
The error message that was shown wasn’t very helpful:
Something went wrong, perhaps this email is already registered, try the forgot password link
No matter which email I tried, the error was the same.
Would it be possible to display an error for the invite code field like when a required custom field is empty?
Maybe it would also be helpful to add an asterisk after “invite code,” since it is required too.
