I would like to nominate Cyborg Ninja for the Roleplayer's badge. He's contributed a few Rps of his own to the Dantooine theatre company such as
A league of their own

The Forsaken Ones

And has also taken place in quite a few of them as well such as the first Magical Strike Force S, Shinobi, Heavy Midnight and quite a few others.
I would also like to recomend Ping for the Roleplayer's badge. He's taken part in quite a few Rps as well such as The first Magical Strike Force S, the Forsaken Ones, Battle Suit Utopia and one installment of the Sith Resurrection.
