How does someone enter a challenge to the web site, I have one but I dunno if I should email the people or if theres a special way?

Well you simply send it to erik or theblacksheep (pm), you put your chall + a title + the solution.
That's all

well thata was straight forward...thank you

I would also tell them how to solve it and stuff like that.
Just sending in ur challenge without, looks a bit urm....dumb
My 2 1/2 cents
