BuddyPress.org

I am looking for very basic functionality. Since there are other larger communities that relate to the one I want to create, I would like to aggregate the events they organize in a prominent location on my buddypress install. Can anyone suggest a way to do this?

Basically I need a way for me or other users to be able to submit an event with name, date, location and other details. A way to add events through RSS would also be great
