MyBB Community Forums

Today I downloaded a 'Greetings Online v2.1 v2.1' and would like to change that when I send greetings to the nickname is the same as the forum did not write what we want in the field already is just the nick of the forum, I used $ mybb-> user ['username '] but it is a mistake
