By following people (visit their profile) and select follow, you can create the board you want to see. If you follow lets say 20 people then by clicking on 'Following' in the sidebar you will only see the post from the 20 you follow.
Initially this seemed like a great idea as I'd get an email notification if a thread I was following received a new posting.
However it seems to have stopped doing it. Definitely following a thread which has had new posts and I've had no notification (not in spam folder either).
As far as I am aware email notifications are only available for the following: replies, quotes, private conversations, bookmarked discussions and events.
I can bookmark a thread via the little star at the bottom and have done for a few threads, including this one.
I'm getting notification of updates to this thread but not reliably getting them from the UK Racing forum.
Updating an old thread, my followed threads have stopped reporting updates again. The last one I had was on 24th August although I know one of them (yours) has updated daily.
