Length of usernames
John,
Is it possible to create 'aliases' on a user name, e.g. corresponding with the domainname, including tld (and if there are more domain names under one user, there would be more 'alias' names). Login in with an alias, you should go directly to this domain.
This way you keep the usernames at 10 positions and give users a nice option to go directly to their domain as well.
