While many will say that running UX Tests on UXers is a big no no, I would argue that there is a lot of value to testing one another and critiquing as we go. The best way to become a better tester is to test more frequently and learn from your mistakes. Similarly it should be noted that taking tests created by other UXers is a great way to develop alternative ways of looking at problems.
Personally, I would love to see examples of on-line surveys/tests that folks have either run in the past or running currently.
