Post installation

I am having trouble conceptualizing how the following would work in Drupal:

Let's see I have a series of static pages assigned with a given taxonomy label ("FAQs," for example).

I would like users to be able to quickly navigate to all designated as category "FAQ."

How would I go about creating a menu item for this? Menu items require the listing of a specific node; in this case, I want a number of items to be returned.

Thanks.

So my site has been live for a week, and I've noticed a large number of spambots attempting to create user accounts. None of them have gotten past the creation stage (all have the last login set as "never"), and so it's not a problem in terms of actually cluttering up my site, but I was wondering if there's a way of stopping it from happening in the first place.

Comments and all that are set for authenticated users only, by the way, so they're not posting anonymously.

Hi,

What I want to do is include somephplibrary.php, and have the functions within, be usable on any page of my drupal site. I thought that simply using <?php include "..../somephplibrary.php"; ?> should do the trick, but it doesn't work. (yes I have the input formats set to accept php code)

So to keep it simple:

1. Where to I place PHP libraries in the Drupal file structure in order for them to work?

2. What files (such as common.inc) would I need to modify to tell drupal to include my PHP library?

Leaving comments was possible in the past, indeed some of the articles (well one) on my site have comments on them. Currently it is not working. I've tried:
Enabling all the check boxes under Admin-Access Control (even for anon users).
Turning off all other modules.
Turning off Comments and restarting it.
Changing the comments box from being it's own page to being situated under the story itself.
Disabling and re-enabling Clean Urls
Searching Google
Searching here

Does someone have to be logged in as an administrator in order for the cron-based search indexing to take place?

That would seem to be the case, in my Drupal instance.

i want to make a barter site for a specific item, lets say bouncy balls. so far i have made a custom node using cck called "bouncy balls" with a custom field "color" the field is a text field that they can freely enter in whatever they want. i then have a category for either "want or have" with is a pull down list. i figure this way users can create two lists, want and have lists -- i'm assuming i can make a link so that users can view their want and have list using the views module.
