I can't send you my post. What can I do, Writeacher? It appears a sentence saying that I've made error 403.

What does that mean?

I'm not sure. We tutors were going through that a couple of weeks ago. It was very frustrating.

Try this: When you write up a post, do so normally and click on POST ANSWER -- if you get the error 403 message, click on the "back" arrow (usually at the top left of the screen) and your text should still be there. Copy and paste it all, and then click on Post a New Question, and try again.
