Not sure if it's a bug but adjusting lowercase to uppercase for usernames shouldn't be flagged as duplicate.
For e.g. Adjusting seed to SeeD should be accepted.
Not a high priority fix though. I can overcome this by changing seed > SeeD1 > SeeD
But just pointing it out so the developers sees it.
(I think I have opened quite a few topics today I hope Toby and the team don't see it as a spam) LOL
Let me know if I'm reporting too much. Thanks.
