Not much info here, but I can confirm I searched my email inbox. No messages match
@bmwcyclist email address (the one used for registering the account on this forum). Maybe another email address was used?
Or maybe the messages got lost? I did have to completely rebuild all the PJRC main server stuff from backup files. The final backup was a couple hours old when the old server went down for good. It's possible messages were lost in those final hours.
Took about 24 hours to get the new server email up. The website came up sooner, other less critical stuff came later. My understanding is most email servers will give a warning after 4 hours if they can't deliver, but they keep trying for 4 days, with another final error if the remote site never responds. We were down just over 1 day, so anyone who send email Wednesday last week probably saw that 4 hour warning (if their email server follows the common config).
I can also confirm I'm far behind on a lot of communication since this incident last week.
