As for original stuff, well, not really. The main reason why is because no one has actually seen my original stuff. I'm paranoid about the fact that I don't want anyone to steal it and claim it as their own. So yeah... That and plus I haven't really started writing and/or doing anything about it until recently. :xd: (I've been trying to work out the kinks in it.)
Before I made the promotional site, I only shared my original writing with people I trusted a little. As far as "Malarkey and Belinda" goes, I had it the registered with the Library of Congress before creating the site. It's still no pro-published, but at least, with the copyright register, I have grounds for suing anyone who might rip me off. It's an easy process, especialy online, and the fee is small. It's nothin you need to have to have your rights, but it's a good way of securing your rights/establishing proof that something's yours if anyone tries something unseemly on you.
That said, I have the first chapters of an in-progress novel online at Deviant Art without this, but only because I'm really desperate for critique. No one's paying attention to it anyway, even for that, not even my busy online friends, sadly. (Either that or it's so bad no one wants to offend me by saying so even though my comments say I want real critique and to give it both barrels if necessary?)
