IMHO, the forum like this is good for general conversation, but is not good for bug reporting. Because there is no easy way of checking whether the same report is posted, and there is no way of tracking. The advantage of a bug tracker is that ISI and we can easy track the problems. It will also become easy to check whether the problem is already posted. Probably it will be difficult to change the way from now on, since the beta period has already started, but I think it's better solution.
