You can do it on your desktop and mobile browsers, though.

My access seems to be forbidden from using every browser and service provider.  

yes i agree @Matthew A Rodriguez I personally don't like going on the browser on my phone so I normally am only on BP if I am home or somewhere with my macbook.

Something that's built in the site, not the browsers bookmark .Tried doing a search on this topic, apologize if I missed it.Thanks

#1 - this feature does not work with all browsers, so maybe you are using a browser that isn't supporting this feature.#2 - when you make a mistake typing after the @, or forget to type the @ by itself to start (it has to have a blank space after the @), it doesn't seem to work.

Phillip - read this link (browser I'm using right at this instant does not support the @ mentions):http://www.biggerpockets.com/forums/25/topics/74369-how-to-get-the-at-someones-name-when-replying-in-forums
