Re: Using tracket to create a page / assigning categories
I suggest that you fill in a feature request, hrsms, in the wish tracker:
https://dev.tiki.org/Make+a+Wish
And have a look at the options related to categories that you can see in the Categories Admin Panel in your tiki: tiki-admin.php?page=category (Admin home > Categories).
For instance, you can force some category to be assigned within a subtree of the whole category tree for wiki pages, or blog posts, etc. Or you can force some categories to be applied to a certain structure of wiki pages, so that when they create new pages within that structure, they get automagically categorized, etc.
