I know its been touched on but the posts that I actually find rather annoying, are members replying saying PM sent, now surely with the pop up box informing you of a new PM makes these posts are completely redundant.
If you subscribe to the thread you receive, emails advising of the response, if the PM is for you, you get two 1 advising of the new post and 1 advising of a new private message.
I was watching Dave's box break live and found it ok with the merged messages, just knew to refresh page every couple of minutes.
