Part of what I've typed repeats what has already been said, but ... I hope that you find some great stories, and meet some wonderful friends here. I know that I have -- and I'm not exactly the best at fitting in myself.
I read what you've written in your 'Roleplaying Preferences' thread, and that's a good start.

Have you looked at other people's Ons/Offs? How to do it is as simple as starting a thread in the appropriate board -- Lords, in your case -- and put the information you have in the 'Matrix' Ons/Offs into a thread there. Feel free to expound a little, and even put up samples of your writing. Create your own interest thread, and don't be discouraged if it doesn't result in stories right away. Timing and persistence is everything, because things like how busy the site is, how many people are looking for new roleplays, what will draw the people who are looking isn't a constant.
Look through other people's 1x1 threads, and group roleplay threads. Respond to them. Say 'hello'. Ask questions.
Participate in the socializing threads. A lot of conversations, and roleplays, can and do start there. Check out the shoutbox. Say 'hello' there.
Maybe, above all, reach out to other people. If someone is advertising for a story or game that sounds interesting, or at least like it might have some commonality with what you'd like to play, say hello. Tell them what drew your interest, what you might have concerns about, and see if there's a common ground. If there's not, then be courteous and move on.
Trust me, there ARE people here who like what you like, no matter what it is.
And if you need help with the code for your signatures, or want other people to look over your ons/offs, I've found the shoutbox is a great place to find help, though you have to catch it when it's active. Even if the person who can help is not available right when you ask, they may well be later.
