I am working on the AMS portion of my new site.

I've got AMS working (few articles yet) but would like a little advice on doing the following:

a) I'd like to add instructions to use the drop-down box for categories (do I modify index.php in the module directory?)

b) Also, when choosing a parent category, it would be nice if its subcategories were options in the results. This way I can share articles and nested articles easily.

ck, just learning php, truly enjoying XOOPS (I've built geeklog and oscommerce sites before this)
