Since the release of 3.0 and through what was probably a fluck, we’ve been setting up users on a multisite using their email address as their username. We were able to do this from the network admin. With 3.2 we are no longer able to do this. Get the error.
Only lowercase letters (a-z) and numbers are allowed.
Is there a way around this now?
i.e. allow the use of an email address as a username?
