michael:
There is no way to do it via ACP settings right now, it would require a module.
...
2.) Update the video module to have a follow icon like the forum does. Not exactly what you are suggesting because its not connected to the 'Profile Follow' button, but is a stand alone system.
3.) create a separate module that listens for specific events and fires off an email when it finds them, maybe this is the easiest way, just check settings..... not sure....
Option 2 would work for me if that update were applied to both the Video module and the Gallery module. With my tiny group, I'd actually prefer it NOT be connected with Profile Follow. I'd rather it stand alone for maximum notification.
Option 3 would work too, maybe even better, simpler.
michael:It would make your email system much more active, currently with the mailgun system you only get 10,000 emails a month before they start charging per email. I worry that could be an issue on larger sites.
Not a problem for my tiny group, but I understand it could be for others. In my little site, things can get quiet for weeks. If someone comes in and posts a photo, I want everyone to know so they can come in, comment, and learn.
michael:The module might be something others are interested in using too. not sure. We do have a "Sponsor a module" system where you can sponsor a module to be built for the community if you (and maybe anyone else interested in it) can pay for a module to be built which then becomes available to everyone.
How much might it cost to "sponsor a module"? Don't know whether that's within my capacity, but it's a great idea. We'll see if anyone else expresses interest.
