I'm not sure how it happened, but today I noticed that Drupal's menus were behaving very oddly. After upgrading to Drupal 6 and installing several additional modules, I noticed duplicate menu entries as well as other disturbing oddities. Items I was placing into the menu were not showing up. Menu items that I moved around were apparently saved but they did not appear properly in a dropdown context. 

Developers are all familiar with the default behavior of the drupal menu systems "local tasks" (aka tabs). These appear throughout most Drupal sites, primarily in the administration area, but also on other pages like the user profile.

Generally, developers are pretty good about creating logical local tasks, meaning only those menu items which logically live under another menu item (like view, edit, revisions, workflow, etc... live under the node/% menu item).

I eagerly awaited the videos for the Boston Drupalcon. They never seemed to appear. 

However, the videos for Szeged are already available here ! The quality is very good. Audio is good and the presentation screens are fuzzy but you can get the general idea. 

Very impressive. There are many hours of must watch video here if you were unable to attend the conference live.

There are currently many solutions for restricting access based on user roles, but what if you have a group of users who share the same role (say Authenticated User) but want to restrict their access to nodes on a per user basis?
