Derrick Stuart - He'd be wittier than this and he wouldn't fight with Matt, he never did that back in the old days. Unless he's encouraging "evil flamey Matt" which he always liked to see again.
Derek Sidebottom - Seemed way too uninterested in the board these last few years.
Trips/ethan/etc. - In which case it'd be pretty much the same troll we'd always had
Jamie - I'm not even sure who/what Jamie is anymore or if ANY Jamie post from the last four years or so has been Jamie.
Starets_orange - Long shot!
Mike Bryant - Long shot!
Ricky - Oh god, it's definitely Ricky Ricki Ricke.
