Oh, and FWIW, you've been here long enough to know that you are supposed to ping someone, when you're talking about them.
Balderdash that you have to ping someone when you have something to say about what they said. Who made that rule up, you? Who are you to say what needs pinging and what doesn't. This is a PUBLIC forum, where anything anyone says is fair game, unless being very impolite. That's what the admin mods are for, to control over-the-top comments. But you aren't the arbitor of what can or can't be said. The mods are. If you don't want someone commenting on what you say, don't post on a thread.
