RRC support for Wireframing?

RRC supports creating reusable user interface parts, sketches and storyboards. Hope that helps.

I'm not that knowledgeable about wireframing. Does RRC support it?

Yes, take look at user interface sketches and storyboards in RRC. They provide a way of mocking up a UI and, then when you need to make changes, making them in one place. If you have ever had 20 (or 200) UI mock-ups in PowerPoint, then had to change one element on all of them, you'll appreciate the reusable and inheritable UI parts.

In fact, in the jazz.net library there is a video of the way the RRC product team used the UI storyboards to design the Review and Approval screens and workflow that are part of the RRC 2.0 beta 2 released a couple of weeks ago.
