I have been following this topic and I must say, I'm disappointed that I can't change my username from the replies I have read above unless I become a donator/VIP. Before now, I was thinking about changing my username from CryptopreneurBrainboss to just Brainboss. Guess I'm stuck with that and the next option (creating an alt account) isn't the best either. I understand that it's for security measures so I'm not that mad about it. Just hoping maybe Bitcointalk will grow to a stage just like facebook and twitter, users can change username even though it's a one time event. Fingers-cross
Bitcointalk has its own security purposes that's why if you want to change your username you'll be needed to pay for the extra charges as what other users said, besides if this might happen for free only then maybe there's a lot of users which just like an ad bots spamming here in this thread without knowing who was it. This security purposes helps a lot here in this forum in order to prevent having so many accounts and if the mods caught you having an alt accounts there is a possibility that all of your Alts included your main will excluded in this forum because you're violating their rules.
