Re: Categories don't show
Hi Richs,
I had a look at your site and have actually one constellation in mind to configure such a situation:
Did you give anonymous visitors just tiki_p_view and tiki_p_view_categories permissions, but not tiki_p_view_categorized and then override the global (maybe also the category) permissions with an object (page) specific permission tiki_p_view for this one page?
If so, but you want anonymous to see the page and browse categories with the items, then assign to anonymous the permissions tiki_p_view_categorized, too, like Rick said, and take away all category and page permissions.
For the contact us feature (I had problems with the changes, too) you can look here http://doc.tikiwiki.org/Contact+Us and here http://tikiwiki.org/ContactUs.
