Hi @Wodahs,
Everyone is welcome as a tester, more testers = more feedback.
The actual testing is literally just testing every feature on the new system, such as posting threads, customising your profile, creating a club, a blog, a gallery, etc. whilst providing feedback on the look, feel and how well it functions compared to the existing system here as well as providing suggestions if you feel it could be improved.
Testing will start when I get enough expressions of interest in this thread - I'm hoping for at least 5 minimum testers before starting.
