Now that we have a bit more experience with the new system, does anybody have any additional ideas on how to accomplish this?
I'm wondering if maybe there is a URL construction that could do it. I noticed the the "New Posts" link uses a construction like "http://www.flyertalk.com/forum/search.php?do=getnew" so it is using the search function. I wonder if there is some way to play with this URL to limit this search to subscribed forms (an option in the advanced search...)
