I had actually emailed Karen because I am having the same problelms.

For example, now at almost 1:00 P.M. California time, I am receiving notices of replies to threads I subscribed to that are now over 24 hours old.

Also, when I logged into Pet Talk the little pop-up that says you have a private message did not occur. It was only by accident that I noticed there were several unread private messages.

Also, when I reply to a thread, it will take a while for it to post.
