Adding third node to Windows 2008 SQL failover cluster

I'm planning to add a third node to a two-node Windows 2008 R2 SQL 2008 R2 failover cluster. Does adding this third node to the cluster and then installing SQL on the third node cause the cluster to go offline for any period of time? (I've already run all the cluster validation tests for the new node, including storage, I just haven't added the node yet.)

Adding a 3rd node does not cause the other 2 nodes to go offline.  If you have a 'preferred node' you can set that up but there's no risk in not doing so.

Thanks - that's what I thought, but I wanted to get some confirmation on it.
