Since email notification is no longer working for me, I've been using Forums -> Your Threads to keep up with my subscribed threads. In the past, threads with new messages were in yellow and those with no new messages were in blue. Now, I only get the error "Please specify some words or valid user names to search on. There were no matches for those that you specified."
I have logged out and logged back in and it did not correct the issue.
