I think you should start a whole new thread instead of just changing the topic. It makes it easier to read for newcomers.
Starting a whole new thread every time there's an update? We'd have 7-8 threads of "Beta Tuesday?" "No beta today" "Beta today?" etc. That, IMO, is far more confusing... let alone spammy 
Keep updating your thread, Ke5trel, I've found it handy.
