When doing the signup at clickbank I typed a long username and it only took the first 10 character of my entered name. It does not look professional and so how can I change my Clickbank username. As far as I have seen the interface of Clickbank, I don't think it's possible to change usernames but if you have some way to get it done do let me know. Apart from that can I have more than one account in Clickbank or can I delete my existing account created yesterday and signup for new account?
You can have multiple accounts and so it is better to have new account and delete the current account. See http://www.clickbank.com/help/account-help/account-basics/clickbank-nickname-id/
Hello, You can't change your Clickbank name. You have to register a new account, that's the only way.
