Oh hey, here is a tip. There are TWO ways to edit your posts. The first is the red "Modify" link at the top but the second is the rectangular "page with a pen" which is in the lower right of the post (once its submitted):
The first method tends to be "tempermental" and will tend to misinterpret formatting and not deal well with pasting but its really good for formatting colors or large amounts of text quickly.
The second method is just plain text and it takes no offense no matter what you put in; the only downside is you must do any tags manually.
If I know I am going to paste something and its a new post, I will just post a "." and then use the "rectangular page" to edit and do the paste.
