I received the following email from StackExchange:
Congratulations -- you are one of the top new Programming Puzzles & Code Golf - Stack Exchange users for the week of May 28 2012!
It's users like you who make the Programming Puzzles & Code Golf - Stack Exchange community worth visiting in the first place.
I clicked the link and found that I was not mentioned at all there. Eventually I clicked next week and found my name there.
I checked this question, but it is marked as resolved and the problem I get is slightly different to the one described there:
Just like the poster of that question, I would expect that clicking the link in the email would take me to a page where my name is mentioned.
Perhaps fixing that old bug introduced a new bug?
