Here are a list of new features that we just updated for the Diigo Groups:

• RSS support: by private / public group bookmarks or group tag
• Browse through public groups by category: “Browse by Group Category” in View Groups
  
• Full text search support to search a group: “Find / Join a group” search box in View Groups
• Search Group bookmarks by Tag or Full-text: When you go to a particular group, use the search box on the top
• Pull up all forum posts by username: click a username in a group forum, all posts by that user in that group will be displayed.
• Diigolet now supports groups: go to “My Tools” section and reinstall. I love the new Diigolet… Give it a try!

Group forum full-text search is not being updated in this release yet, but forthcoming… Stay tuned…
