is there such a thing? I know the one for internettablettalk, which is http://www.internettablettalk.com/in...ss&feed=RSS2.0 , but I'd perfer to monitor all posts on the forum as well.

The link you gave is the best way to monitor threads via RSS. As for RSS for replies, vBulletin doesn't support that. We created a hack however to generate an RSS feed for a particular thread, but you need to know the thread id. Here's an example:

http://www.internettablettalk.com/fo...=253&type=rss2

Just to add, you can also filter the RSS for specific forums by including the forum ids such as:

http://www.internettablettalk.com/fo...forumids=15,16

so this one:
http://www.internettablettalk.com/fo...18,12,13,15,16
gives the topics (without replies) of all the forums, right?

Correct. But if you are going to include all forums, just disregard the forumids parameter altogether:

http://www.internettablettalk.com/fo....php?type=RSS2

thanks, even better. I like simple things.

BTW, the RSS reader on the tablet rocks, it even grabs the little icon for the domain url (the black square with the itT icon).
