Since I was able to make this post, I can't image it's the posting password is an issue. I'm thinking it's html now. I asked in the forums, and someone told me it can happen. But I just can't track it down. I've changed browsers, restarted, etc., it's just not cooperating. The html isn't complicated and it's all responding in the preview just fine. It's just not letting me post. :/
I think if it was a permission issue, I couldn't even respond here.
