rogdias replied to me via iNaturalist that he did get e-mails for both the private message i sent via iNaturalist and also via the forum. if that’s true, then his e-mail address must be set up correctly in iNaturalist (and also in the forum).
i also turned on e-mail notifications for myself, and i’ve been getting them regularly for the last few weeks.
there have been reports in the past, i believe, that specific users or groups of users have had e-mail notifications stop working, and staff had to do something to resolve the problem (ex Email notifications stopped - Bug Reports - iNaturalist Community Forum).
nobody else has reported an issue here recently. so maybe it’s just rogdias who has an issue right now.
@rogdias – if you’re still not getting e-mail notifications, then you may want to write help@inaturalist.org to see if maybe staff can troubleshoot something with you.
