The forum does not see how good the name used on the account is, what the forum needs is how much you contribute while you are here, that's what makes you always remembered for giving a lot of education and knowledge to other users.
Contribution is an initiative, you are not required to have it but you must have the knowledge to be here as one of the users who are expected to help other users. But you're right, username is just a name that shouldn't be a benchmark of how much knowledge you have on this forum, in the end it's just a name.
_BlackStar is just a name, but this name has inspired me to have a great journey in this forum even though I am not yet worthy of being named a contributor to anyone and to anything else.
