Drupal 7.x

How do I hide another form's validation error messages using hook_form_alter()?

I setup a test server using ubuntu and I have set a sybolic link to /var/www in my user folder
When I try to ftp files to the modules folder I get an error saying that the permission is denied.
The permission on the folder is currently 755. Any ideas?

Also, should I have made the symbolic link int the public folder?

Is it possible to get page-specific menus in a standard Drupal 7 installation? I have different users that blog on seperate pages of the site. I'd like to have a "recent blog entry" menu on their "own" pages that gives a view of only their own blog-items. Example situation:

I want to use small size user picture in comment,but I don't see any options to choose picture display style for comment only on account setting page.

how to put small size user pictures in comment?thanks。

I'm creating a node type programmatically during my module install and wish to set certain node type options. I've done a lot of searches, as well as dumping variables when saving the node type, to determine how these settings are saved. So far, the only one I've found that works concerns comments. Below is the code I'm using to create the node type.

I have been pulling my hair out trying to figure out how to remove particular components from a form in Drupal 7.

Particularly, I'm trying to remove the "Block description" section as well as the "Region settings" section. (So my clients, when editing existing blocks, don't see these items)

I've tried to follow various tutorials such as the Lullabot tutorial at http://www.lullabot.com/articles/modifying-forms-drupal-5-and-6 - but to no avail.
