Extending Feeds to User Profiles & Using XenForo's Caching System?


Well-known member
I am attempting to create a modification that will pull the 5 most recent feeds from a user's Formspring account (as identified by an identity service) and display them in a tab.

The first problem I'm facing is that I am unaware of where to start with extending the RSS functionality in XenForo. Would I be looking at XenForo_ControllerAdmin_Feeds?

Also, should I use XenForo's caching system to store the feeds in the database and cache the results when called or should I just use a remote call to Formspring's API when the data is requested?

TIA for any input.
