I've added some new parameters to make it easier for people to stick a useful widget-like feed on their website using an rss system.
with the sa=recent action listing RECENT POSTS, you can now add parameters:
u=4,5,6 (this says show all recent posts by users # 4,5, or 6)
tu=10,11 (this says show all recent posts made on topics started by users #10 or 11)
tl=1000,2000 (this says show all recent posts made on topics #1000 or 2000)
with the sa=news action which lists recent TOPICS, you can now add parameters:
u=4,5,6 (this says show all recent topics by users # 4,5, or 6)
Rss feeds now also obey same nofollow rules as posts.
Enjoy!
