Two things that aren't mentioned in the Sandbox but are mentioned in this article from eWeek are Microsoft's experimental service for RSS aggregation (hint, click on the "show" link over on the left side of the page) and this service that let's you store bookmarks (courtesy of the same article).

Uninstall the extension.
Download the latest version of the extension.
It's really a ZIP file so rename it from Extension.xpi to Extension.xpi.zip
Unzip Install.rdf into the same folder as the .zip file.
Edit Install.rdf.
Find the line containing the word maxVersion. Change the number between the angle brackets to a number equal to or larger than your current Firefox version.
Save the file, then add it back into your Extension.xpi.zip file, overwriting the original Install.rdf.
Rename it from Extension.xpi.zip back to Extension.xpi.
Drag and drop the file into an open Firefox window.
This article from Aunty Spam's Net Patrol discusses AOL's (lack of) privacy in AIM. Apparently AIM users who have downloaded or registered for AIM since Feb. 4, 2004, have given up all rights to privacy and have granted AOL permission to reproduce or publish their messages.

Yesterday, I happened to have copied and saved a piece of the TOS language that concerned me. Today, as of about 5 minutes ago, it was no longer on the site. Here's the original language:
"Although you or the owner of the Content retain ownership of all right, title and interest in Content that you post to any AIM Product, AOL owns all right, title and interest in any compilation, collective work or other derivative work created by AOL using or incorporating this Content. In addition, by posting Content on an AIM Product, you grant AOL, its parent, affiliates, subsidiaries, assigns, agents and licensees the irrevocable, perpetual, worldwide right to reproduce, display, perform, distribute, adapt and promote this Content in any medium. You waive any right to privacy. You waive any right to inspect or approve uses of the Content or to be compensated for any such uses."

Right, check out Slashdot again. This Slashdot posting contains a link to this eWeek article which says that AOL intends to make changes to clarify their intent. It appears those changes have been made.
