How Do I ......?

[ATSF5700BOB]

 Good evening all !!! I know this has probably been asked before, but I am not a P.C. genius, and therefore would appreciate anyones reply.
Most people know how to add their roadname, favorite railroad, or even witty replies at the bottom of their posts. I do not know how and would like to learn. Many thanks in advance for all of the replies I receive.
