I've enabled RSS feeds. The feed is here:
(Dead link: http://www.blackjackinfo.com/bb/external.php)
Personal use is allowed, but republishing anywhere is not.
I'll keep an eye on the impact on the server, but I don't expect this will be a problem.
If you want to specify a particular list of forums, do it this way:
(Dead link: http://www.blackjackinfo.com/bb/external.php?forumids=5,7)
You can find the forum numbers by hovering over the forum name and noting the "f=?" parameter value.
Let me know if you find it useful.
