What version of Jive software is this?
Is this a fully custom template / theme built by e!Online or is this something offered by Jive Software?
Unfortunately it is tough to tell which version of Jive this instance is running, although it does look like Jive Forums.
It looks like some light themeing to brand the community, and much of the UI looks very similar to the out-of-the-box experience.
Hope that helps,
