I guess this is really more of a general meta.stackoverflow question:

Putting @ before a username in comments makes it show up in their inbox. What about if the username contains spaces - does the same thing still work, or are any modifications needed? E.g., if I want to point something out to user "Joe Shmoe", should I use "@Joe Shmoe", "@JoeShmoe", "@Joe_Shmoe", or just "@Joe"?

  • @WAF: nah, I just used that as an example. Although that is pretty funny that someone actually took that name...

Strip the spaces out. In your example, you want @JoeShmoe.
