It’s a courtesy ping because wtc911 was involved in an exchange with you in which I also took part. Calling me a coward for issuing a courtesy ping shows that your reasoning powers are challenged.
Bull. You don't need to ping anyone to a post in which you don't mention them by name, and you know it.
You're pinging your buddy for the same reason that all craven cowards do... you can't go toe to toe with someone who's willing and ready to fight you fair and square.
Don't mess with me, troll. I've been walking this earth long enough to know your type when I run across them.
