Sandbox

this is a really nifty forum setup they have going on in this site. This site looks like its joomla. I'm wondering what extension are they using in this instance?

when i mean this site i mean this (http://forum.joomla.org) site. the one you are using now!

I think this forum method is Proprietary for joomla.org. if you need a forum component like this use "fireboard" component.
it's the best one to run a forum in joomla site, you can download it free from bestofjoomla.com
 

Mod note: moving to correct forum.

Please see: http://help.joomla.org/component/option ... temid,268/

It's not proprietary (although the bridge may be) ... the forum software and version can be found by scrolling down and reading the footer.
