How do you link to names within a post?

I know that you can copy and paste links, but is there another way? Thanks!

Normally when you post the links will automatically form after a few minutes. (Exception: From my experience, if you edit a post and add a name, the links may not automatically form. In that case you can enter the [name ][/name ] tags around the name to ensure it links, removing the spaces in the example which I put in to make the tag example show.)
