Site feeds

How to construct per board feeds for example to follow PVP discussions?

1. Get the board id of the PvP forum from the forum index: http://wowraid.com/index.php?board=4.0
2. Add that to the end of this url: http://wowraid.com/feeds.php?b=4.0
3. Tip: appending "&posts" to the url shows all posts, not just topic openers. Using the previous example: http://wowraid.com/feeds.php?b=4&posts
