There is a problem with PMs right now.
I don’t know the extent of it because I don’t have sysadmin privileges. David will fix it when he gets time. In the meantime I can forward email addresses upon request, as I used to do before we had PMs (but then you will lose mutual anonymity, obviously).
Also in the meantime I suggest not doing a reply to a PM you received from somebody but instead sending a fresh PM. My tests show that the initial PM works but replies posibly don’t get routed.
This is also worth a read, for whitelisting the email address and because some email programs break the mechanism used to route the reply (while preserving mutual anonymity).
Some work has been done on this and it’s all working properly now. Please do use it and if there are any problems let me know.
No issues encountered, and once again thanks for the good job.
