New XML Form not showing up...

I've created a new form... in fact, a few new forms -- some copies of existing ones and some from scratch -- and can't seem to get them to show up as an option when doing a "New".

I've checked the rules under System Administration\System Configuration\KM\CM\Form-Based Publishing\Forms Availability and everything seems to be fine -- the out-of-the-box rules are the only ones there, restricting some room forms to specific locations and enabling everything else globally. I've tried modifying the rules to specifically include the new form, but to no avail.

What else might be affecting the visibility of this new form?
