The Forum will be be upgraded. This will result in some down time (it is just a minor upgrade, but I'll do a full backup first which is what necessitates the downtime). I will place the forum in read-only mode before the change, and bring it out when I am satisfied it is working properly.
Currently it is scheduled to be at 5:00 UTC on Tuesday Oct 15, which should be late at night in North America and early in the morning in Europe, and a useful time for me in Australia, so hopefully a minimal disruption.
I will also reply here and on the the Keyboard Maestro Mastodon account when the process starts and finishes, though the forum wont necessarily be accessible.
Refer to the System Status web page on my web server, which indicates the known status of various servers and systems. If you detect an issue, that is a place you can report it, and I will be promptly informed of the issue and can follow it up.
