*** Dear UD staff,
You need to fix your software.
Your user interface is telling me (falsely)
that this example doesn't contain "space out."

If you need a programmer who's up to the task,
drop me an e-mail and I'll send my resume.

*** BUG NUMBER 2:
I checked on my submission later and found this:

"Your submission was cancelled before it was reviewed by editors."

Uh, no, I did not cancel my submission.
Your programming staff needs to know about this bug.

If your way of handling bug reports is to simply delete them, i.e., to blow them off,
I will post this publicly.
