Not sure you know where to read about rules yet.
Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ[Bitcointalk sticky threads] Newbies - read before starting.Something about my coursemate intrigued me and I wanted to know his username on here. But he refused to tell me, for long I've wondered why ? "Does it really matter?"
It's strange that your friend introduced you to this forum but refused to tell you his username here. Most of people will not care about anonymity when they are online but I understand if your friend actually care about it and his practice is truly helpful to protect his anonymity.
And by and by I see why it's better he didn't tell me. I am growing knowing that he's grown overtime I don't have any form of unnecessary competition with him
If you don't know your friend's account username, you did not know what rank he is at and can not make any comparison between your friend and you.
