Welcome to the guild. You should be able to find whatever information you need, either from guides or members.

I remember when I was new to site-based RP (though not role-playing or writing), somewhere in the region of 10+ years ago. I actually started out joining a very advanced RP forum at that point, where you needed really large character profiles to register and had to post within the region of around 5 paragraphs or so. With that in mind, you probably picked a good place to introduce yourself to the concept, since there's places for beginner, intermediate, and experienced RPing.
