Well, I'd be willing to help you! :3 I'm very patient and plus, well, I've been there. I was just really lucky to start out on a board that was very accepting, and even though I sucked I got to play with some people who were just <I>awesome. They were patient and showed me the ropes. So no matter how bad you are, you can still learn and get really good. It just requires patience, practice, and getting to play around people who have more experience.
So anyhoo! I guess my first tip without seeing any of your RP would be to use punctuation and capitalization. :3 It makes it nicer and easier to read. For spelling, if you have Microsoft Word or Works, just copy and paste your posts in there and run spellcheck. ^_^ Even I do that for my posts!
But anyhoo! Would you like to do a thread? Or do you have any questions in particular? Certain areas you need help with?
