How to report someone who is not in your circles on Google+

Google+ to mention someone in a post or comment, you can either use the classic "@" (as in Facebook) or by using the "+" and then typing the first few letters showing you the same results.

But if someone is not in your circles will not appear in these results.
The solution then this is the report by the ID instead of his name.



Suppose that we have the profile https://plus.google.com/104523600175524643618. Deletes the https://plus.google.com/, and keep only the numbers at the end, and write them in our publication with a "+" in front.

Probably not show you any results dynamically, but once you press the "Share" tab will display the user's choosing.
