I have found AUM to be very informative, and I believe that there's a new one just about every month... however...

I think most of us would find it extremely helpful if we could sign up for a mail list where we could receive email notification when an update is released... it would save some of us (like me!) from wrestling with bugs and problems that have already been fixed, but we don't realize it until we dig through the forum in desperation looking for answers (or post redundant messaages), to find that a new update was released that we didn't know about.
