Someone created a tag named
html+php. How did they do that?
Using the "edit tag wiki" link on the Tags tab, I was able to get to the tag info page. Unfortunately the trick of viewing the top users page doesn't seem to want to work, as the sole question assigned to the tag doesn't have an answer.
How can we find the question, and how did the user that asked the question manage to create a tag with a plus sign?
