I agree that this is a missing feature that makes this forum quite a bit harder to use than other forums of this sort.
in reply to Email notification of replies pertaining to me
I understand that there are lots of issues with sending emails and I know about the /msg box. Basically, I can live with notification in the msg box only but what I do miss is the ability to subscribe to threads you want to follow even if you are not the OP or if the posts aren't a direct response to one of your own posts. Unless I'm missing a setting, this is currently impossible and you have to trawl through "Recent Threads" or chase up threads you have posted in via "Nodes you wrote", which is very slow. Please correct me if I have missed something obvious.
