I’ve gone back and noticed that sometimes a handful of people had responded to a previous comment and I never realized it.
As it stands, it seems you only get notifications if people actually manually mention your username. Is there any method to get post/thread reply notifications?
It took me over 2 weeks to figure it out, myself. Don’t be hard on yourself!
Took me a couple of days, was thinking eh, why was everything so quiet. Definitely should be on by default!
