We’ve been adding features, which, if you haven’t seen them yet are:

• You can post to your blog, including Blogger, Typepad, Movable Type, LiveJournal and any Atom Enabled Blogs. Go to the blog setup page to get it started.
• We now support RSS/Atom for groups. RSS and Atom feeds are now available. Flickr supports RSS (0.91, 0.92 and 2.0) RDF and Atom. Links can be found at the bottom of the group page. If you don’t know what RSS is, read about it here.
• Groups are now sorted by most recently updated, and there is an indicator that shows if there are new posts.
• You can now get all recent updates from your groups on a a single group update page.
• All group users can now preview and edit their discussion posts. No more broken links, typos etc. And you can go back and edit your own old posts too.
• You can now see, from the group page, the number and the names of the group members that are online.
