One of the most-requested features for the discussion forums has been a better email notification system, particularly the ability to have those for all topics -not just the ones you have started yourself- and the ability to turn them on some time after the initial post.

As of today, the Saloon has Topic Watches. At the bottom of each post you'll see a button called "Watch Topic". Clicking it will cause that topic to be watched for you, meaning you'll get an email to the address you entered into your Saloon profile.
You will then be shown your personal Topic Watch page. It lists all topics you are watching, has links to them, lets you turn email notification on or off, and delete them. The page is also accessible directly through the "My Watches" link at the top any Saloon page. If you turn off email notification for a topic, the watch becomes more like a bookmark.

There's also a little icon for posting a topic to the social bookmarking site del.icio.us. If you haven't used del.icio.us so far, by all means, check it out - it's the 21st century version of browser bookmarks.
