Hi
We obviously get notifications when somebody likes our posts but not if they are quoted, On another forum I use we are notified whenever somebody quotes our post and there is also the option of mentioning someone (by using @username) if you want them to see your post.
It's a really useful option if you don't want to follow an entire thread just to see if people have responded to you, particularly in fast moving/long thread.
I don't think it's difficult to implement (and I can actually find out how if necessary) so wanted to suggest it as an option for this forum.
Cheers
Rob
