Board Index Empty

I'm sure this is a dumb question and this is my first effort at ever setting up a forum, so I feel a little in over my head.
I did get the user settings fixed so I see the board index now from the menu, instead of the redirect loop error but I don't see any of the categories or forums showing up.
Here's what I have thus far - http://108.167.181.241/~dbvet/for-veterinary-professionals/vet-dental-forum

I actually have permissions set to public allowed until I can figure out how to set up the whole member log-in part of the process. Would love any tips on that if you have them. I'm not sure whether I should use the basic Joomla! registration set up or another extension that allows more control over who can register an account, use a password or get administrator approval.

Any help would be greatly appreciated!

Hi c5web,

The board appears to be ok with 1 forum and 1 topic inside!

Yes, sorry I figured out it was category permission, but I couldn't get back into my question here to remove or update it.
However, when I try to post to it, the topic includes the following: Can you assist, or should I begin another topic?
