Post installation

I set up my website, defined a vocabulary named "articles" and added terms for different categories for the articles to be in. Set up article module, and it was working great. I then moved my website from the subdirectory to the root directory, changed the settings.php, and it all seemed to be working great. Then I noticed when I go to www.mysite.com/article, the first category is repeated over and over and no longer has all the categories listed.

I can't figure this out. Is something broken? Any ideas?

At the AV Club Weblog, (http://avclub.com/content/blog)

When a user submits a post it says "posted by: User Name"

I have a demo installation, and when I make a test blog post, it says "User Name's blog" When viewing the from the main page.

When viewing the individual post, it says "Home » blogs » User Name's blog" above the story title.

How do I change this? Either setup works OK for me, since the site will have multiple authors, but I would like to try out both.

When I access administer-->blocks, and configure my enabled user login block, I tick "show on only the listed pages" and add "blog" and "blog/*" to the list, the login block disappears altogether. Is there a way to remove the block from the whole site except the blog?

Taxonomy Based on Taxonomy? I am certain that this has been asked before, and did some searches, but never saw exactly what I am looking for...

Here is a quick hit of my hopes:

Use FLEXINODE to create a node type called Animal:

Add a Vocabulary called Animal:
Add term: Dog
Add Term: cat
Add Term: Pig

Add a vocabulary called Dog:
Add Term: datsun
Add term: retriever
Add term: mutt

Add a vocabulary called Cat:
Add term: tabby
Add term: stray

I recently (2 months ago) upgraded to 4.6. The biggest chunk of my website consisted of blog entries. I've successfully posted several blog entries after the upgrade but on occasion have received error like the one below:

Hey there. Building my site, I've run into a little problem. I have avatars displayed on everything - comments, nodes, node lists, etc. (Can't remember how I turned it on in nodes, or I might just turn it off and leave it on only comments, but anyhoo...) However, organizing my site, I've had to build certain summary pages (i.e. http://electricteaparty.net/review ) with php snippets. I actually hate this, because if I could find a module that would automatically build pages for each vocabulary that just listed all the sub-terms that would be far preferable. But the best I could find was the Article module, and it won't let me build seperate index pages for each vocabulary. Anyway, back to the point (I tend to wander).

If I have to use pages with php snippets to index my site, fine. But it's annoying that these indexes show my avatar and user name, because I want them to be generic indexes (not "posts by me"). Can I turn off avatars and usernames on these pages somehow? How does drupal.org make the handbook pages generic - do I edit a template file or CSS file somewhere? It would also be great if I could get rid of the "categories:" thing at the bottom - I don't want them to be in any categories, because they're just index pages.

Like I said, it would all be so much easier if some module automatically generated lists of terms for each vocabulary!
