I have posted an invitation on their forum before.
I think we have had some responses from that post.

What NeoGen says is true.
Many people on that site belong to other teams.
People on that forum even created a team in Folding@Home that has the forum name as their Team name.

The "AMD Development" engineers that work for AMD and also have some pages there even have their own team.

None of them do work in as many projects as we do, but they all know we are here, so that is good.

If any of them chose to join us I expect that we would happily welcome them.
