When adding people to a conversation [more than 2 it seems], it shows the "new message" alert in the inbox, but does not show the message [the popup display the link for the new message] to the members being added, it just displays older messages [if any]. [me being added]This has been true, and I just couldn't figure out what the message was, so they were unnoticed. I realized I have gotten to see these alerts in the past, and did not see any new messages [in the popup]. But today I added someone, and I expected him to respond, he never responded. Then when I asked him why he didn't respond, he said: I had sent him a direct link to the conversion after questioning him why he had not answered, and quite honest, I was getting irritated why he was not answering. But it wasn't his fault at all. There were 3 people in the conversation including me, the guy I added was the 4th. Kinda had the same issue yesterday, but I wasn't sure of anything. Now I am positive that there is a bug there.
