Thunderbird is an email client with
built-in RSS support. The instructions on the link given are excellent, so I won't tell you all the setup steps.
What you get when you're done is the ability to read the latest happenings on this site (and your other favorite RSS-enabled sites) right in your Thunderbird inbox, as if they were emailed updates. So if you've ever wanted to get email updates when there's new content on your favorite sites, this is the plan for you.
Reading RSS in Thunderbird feels like reading mail, but the underlying technology is RSS feeds. Thunderbird tracks the read/unread status for you like with email, so it's easy to breeze through looking for new items. And you manipulate the messages with familiar tools, so toggling messages between read/unread or setting flags is all just like handling mail messages.
And your saved searches can filter the articles in your RSS feed accounts too. So if you are looking for the latest posts by a forum member, you just need to subscribe to the forum latest posts feed, then save a search that lets you filter down to that member's posts.
And because they look just like mail, you can even forward the items in the feed folders directly to your contacts.
