Hi. Thanks for the great information.
For your "7. Don't post more than 4 times in 24 hours." point. Do comments count? I know they add to your post count... I'm hoping the 4 times in 24 hour thing is only for blog posts from the "Submit a Story" link and not comments.
This was 11 months ago so you've probably figured this out by now...but just writing in case other people stumble on this like I have. I'm a newbie too, but I've learned there are no limit to comments and in fact you can go crazy writing comments - as long as they are coherent, thoughtful and people can tell you actually read the post ;)
