Welcome to the site Hawk :D We can be complex, like complex carbohydrates, the ones that are good for your health! Don't feel like you need to understand everything right off the bat, it's easier to get started with some of the basics and delve into more stuff when you feel comfortable :3
Yes. Well I read all about Pendragons and such. I'd like to be one. But then there's the more confusing question: Can you explain how you roleplay here exactly? I mean, I'm no stranger to rp, but some sites have their own unique qualities on how to do it....
What sort of roleplaying have you done before? I might be able to explain better if I know more about your background. :) We're a writing-based game, so you create a character (a Pendragon, or another race of your choosing), and then you can start writing in the forums as that character. We're rather open and free-for-all though, (no dice, or dungeon master, etc.), and some people can find that level of freedom a little intimidating.
I've done Star Wars RP, High-Fantasy RP, and little Modern Fantasy RP. Luckily, they were all free-for-all too, but some of the rules were hard to not break..... Sometimes, it was like you were in a mine field, and one wrong word would have every moderator and administrator blow up in your face. I call those times, "The Roleplay Dark Ages".... :P
Ahh. :) Well we're a little similar to Star Wars, but our rules are super relaxed. No one is going to blow up on you if you happen to get something wrong either. I mean, I don't even know everything that there is to know on the site. You have almost limitless creative freedom when it comes to creating characters here too. There are just a few broad rules: http://shadowlack.com/rules/ I think that most of them are fairly reasonable (like how we don't have time travel, etc.). If you do have questions about rules though, or would like something clarified, myself or someone else will happily help you out. :)
