Trerro, exactly when will the site be moved into Rackspace's Cloud Service?
It won't be. We're moving to Linode when we get the announcement, a much better company.
When will the experience system be up and running?
I'm going to do this along with the forum upgrade.
When will the site be upgraded to Version Two of the forum software?
I don't know yet. They haven't produced the API for v2 yet, and until they do, I can't update my stuff. It will hopefully be available soon.
Ideally, I want all 3 of these to happen simultaneously to minimize downtime, but that requires us to not not get the Rackspace announcement before the API comes out.
