...in my subscribed threads. Am l missing something, or is this waiting to be fixed?
Yes, can quite understand that as it happened to me too :)
From your My Profile page, If you go to Edit subscriptions a whole new world awaits.
But when you find this bit, be very careful.
It is possible to alter notification settings here for Users & Threads - if u alter the User one to 'immediate' in the drop down in the Frequency column, you should receive email notifications.
Provided that you don't click on the Stop all Subscriptions Email tab - it's not a drop-down.
Whatever you do, suggest don't accidentally remove contacts by clicking 'X remove' on the right hand side of each entry on the list.
Hope that works :)
