Wow I am dragging this post out from the archives....
I was looking for the same, mainly for the Announcements board (for WB) so that when and if any announcements come about, I am notified via my daily read RSS feed Reader.
Actually I thought phpBB had this facility already - might be an add-on but either way would be a handy add-on.
While I'd like to visit every day/week/month my eyes can only view so many sites per day/week/month
So anyway sorry to drag this request out again - but if something can be done for the announcement boards at least it would be good.
EDIT: Another option could be a subscription option to a specific board and we are notified by email of any new threads/posts in that board... might be a way to get around the RSS issue ... not that I thought there is one...
EDIT: Lots of options here -
