Who is he? And when did he become a moderator?

As you can see here, he's one of the moderators.

So was he a longtime member of this site? Forgive me if I've not seen him/you in recent times, maybe he's/you're not that active in the forum or the highlight page.

He's one of the employee working for Footyroom.

Ahh I see. Thanks for the clarification Tuan
