New Setup, unable to post

I have attempted to post with a newly created user and it says:

Can't post

Sorry, you cannot post at this time.

However, I completed the e-mail registration part. Has anyone else run into this problem? Is there any way I can debug this?

If you'd like to try, the new code is at:
