I'm all setup with profiles and accounts to be a tester but was wondering about a couple issues. 1) If we're testing something is in active development like Natty, should we install the Milestone release and then not do any updates before doing the testing or should the system be full updated? 2) How important is it too remove all configuration from the home directory before doing testing? I haven't looked through the instructions for every test yet, but I'm wondering if it's possible that existing configuration could mess up the tests? Thanks, Andy
