It's been quite a while since I have received any notifications for new posts to topics I am subscribed to. After a bit of testing last year I think the conclusion was that the forum software needed updating.
Is anyone else having this problem - I assume it's affecting others ?
If it helps I run a couple of domains that utilise these type of scripts and am willing to lend a hand if that helps.
For me it's just about letting people know there are replies to posts so that help gets communicated faster.
