When I opened gmail this morning, I saw the usual "You have new message" notification — http://store.picbg.net/pubpic/F3/D8/21675f680b25f3d8.png. However, when I followed the link, I saw there was no such message — http://store.picbg.net/pubpic/4D/EA/a9846246fd744dea.png.
How is this possible? I tried sending a random message to a friend of mine in order to see if I can somehow delete it in the first few minutes but nah, I couldn't.
PS: I also noticed that I haven't received an email for this comment — http://codeforces.com/blog/entry/46407?#comment-308043. Is it some sort of a bug, I remember this has happened before?
