You can obtain RSS feeds for most parts of your Ning network.
Just go to the section of interest (eg Blogs) scroll to bottom of the postings page and you'll find a blue RSS box symbol from which you can right-click and copy the feed link. Likewise for forum etc.
Note this will only work if your network is public.
George is on the money. If you have some additional skills, you might be able to create an RSS feed if you need something very specific. Here's a list of all of the possibilities that I think is current.

Thanks, Hugh. Try this one: Overview of Available RSS Feeds.
Thanks! Never noticed that little box before... However, when I click it, it just opens a very messy page of HTML code. Also, my network is Private. The homepage is visible, but anything after that requires a subscription.
As George notes, you won't be able to pull a public RSS feed of your content if your network is private.
Also, if anyone isn't sure how RSS works, these guys made an intro video that might help.
We are having the same issue. I'm trying to figure out if there might be any sort of work around that could make our site more like "semi-private" so we can get the benefit of the rss feed feature without giving everything away to non-members. I'll come back and let you know if we find anything...anyone else please chime in if there is a partial solution to this you can think of.
The other way to share information on a limited basis is by using a group, to which you can restrict membership. This means public visitors to your network could not see the content posted within the group.
However you can't use RSS feeds for sharing the information, because that only works on public networks.
I've been asking NING about this too and still waiting for something useful. And it doesn't have to be RSS, as long it's something that allows my users to subscribe to the activity flow (for example via email) instead of having to log in to check.
