Gabriel, I'm 15. Of course I don't have a registered company yet. As far as I know, however, there is no harm in claiming that I am the CEO of a group such as Ghz.
No harm, and no point. Much like me claiming to be a member of the Spice Girls. ( Zig-A-Zig-Ahhh! )
And kindly do not refer to me as "he;"
Certainly. By which personal pronoun would you prefer to be referred? "You" is out because my comments were directed to someone else. "She" seems inappropriate for someone called Adam and I don't particularly like referring to someone as "it" although I can make an exception if you're particularly keen. Since you like the imaginary company angle, would you prefer "they"?
it smacks of behind-the-back comments.
It's a public forum of which you are a member and it's in a thread which you started. It couldn't be less behind-your-back if I superglued it to your nose.
