You can click on the 'notify' button to get notifications of further posts in any thread...which would include answers to any posted question in same thread
Thanks, that's useful to know. It isn't quite what I was hoping for, though. It's quite easy to forget what thread you have posted in, especially if you haven't logged in for a while (I've just been off-line for a couple of days), and also when a discussion where you have posted is one which has gone off topic, so that it isn't obvious where to find a post.
Having a notification which specifically says a reply has been posted to a post you've made would, in my view, be even more helpful.
