Dan usually does a monthly announcement here on the forum to fill us in on what is going on, latest schedule changes, etc. and if it’s an important announcement he mails it out to all owners. The last one was at or around April 23rd, I think . (I seem to recall that one was mailed out, but I didn’t keep it.)
Make sure you have *@glowforge.com white-listed so you don’t miss anything important, but you can also read it in the Announcements section on the forum.
