Rss feed to feedburner

[fahl]

I have a feed for my board at feedburner using external option in vb,but it is only taking stuff from a couple of forums.
Is there any way i can choose which forums to thake threads from.

Doesnt work as it reads it as invalid rss feed

Only forums that are viewable by Guests can be seen in the RSS Feed.
