Super useful theme, just what I was looking for. I used to do something similar in a typical blog format w/ custom archives, this is so much better.
One problem - I've noticed that if I accidentally submit a ticket without all required fields, instead of giving an error and letting me resubmit, the ticket just goes blank and nothing is saved. Obviously I can learn to work around this, but as soon as I want to let anyone else use the tracker it's going to be a big problem. Any suggestions?
