Welcome to STC. You're already started on the process to getting approved. We like to see a bit of positive involvement with the community here before you gain full privileges to make role play posts and such. So, here are a few areas that you can make some meaningful, quality posts in. It is more about quality than quantity and usually just a few in a variety of areas will get your account flagged and then the Administrator will be able to approve you when they next get on. So, these are each hyperlinked so that you can go straight there and see the various areas to post in. If there is not a thread to your liking in some of them, then go ahead and make a thread of your own.

Just on a side note, don't worry about not knowing anything about role playing. Everyone has to start somewhere and we're all addicts that are more than happy to get you hooked too. So, what kind of genre's or things do you find interesting?
