As you might have noticed the forum was down for ~2 hours this morning. Unfortunately a routine Discourse change (the software we use for the forum) to change our SMTP server didn’t go very smoothly and had some knock-on effects. Now all back hopefully (and with working email again).
Also, based on my own email box, the forum seems to be sending a ton of emails out now about posts I’ve interacted with - and I have no idea on how to clear the queue. Sorry for the inconvenience.
