Well... that's the question I've seen quite a lot here. After scanning through myriads of portfolios and profiles I've got an answer. Beware, it's a top secret info!

1st: you must be a girl. All ork boyz automatically got 1d20-10 to charm, luck, dexterity and so forth.

2nd: you must be cute and attractive girl. Just like this -> =^_^=

3rd: just post your cosplay (nekomimi, Rei, Asuka etc.), swimsuit and bikini photos into the gallery. If you're an adult you can tease with (semi)nude shots as well.

That would be enough to create a hype and groove around you.

If you can draw, well it's a minor bonus though you can impress some art geeks and turn them into your minions.
