Do you play on your MMO's public test server?

Even after they're officially launched, many MMOs still maintain public test servers where volunteers can help the devs test out upcoming content (or at least sneak a peek at it). I am not usually one of those players, but long ago I spent a lot of time on Ultima Online's test center. UO made it super easy to test by allowing players to boost their characters skills and giving them a bank full of resources. In fact, I knew players who loved the flexibility and lack of grind so much that they considered the test shard their home shard in spite of the wipes, and even today game-wide events are still held there so that people from all servers can attend.

Do you spend time on MMO test servers post-launch?
