Limit recent posts by site

Hi all,

First off, I am happy to be a new member of wpmudev. I look forward to being a part of this community and thanks for taking the time to address my concern.

We use our MS install to run our blog network on our news site, but we also use it to quickly create smaller, info sites for projects that we run. It is extremely efficient to be albe to do this on one MS install. That being said, I would like to display recent posts for those sites that are part of our new blogging network and not from our other mini sites. What is the best way to do this?

We are currently using the Blog Types plugin and each blog in our news network has its own type. Also, our list of mini sites is relatively small and we could simply limit them by using their site id. Any help or recommendations would be greatly appreciated.
