I don't hold grudges, at least with those guys who have enough intelligence to respectfully disagree. Even though I don't agree with them about some things, I'd be happy to share a campfire with them. Even MilDot. [8D]
Those that have repeatedlyproven themselves to be jerks, I just click on that little red hand right above their name and block their posts. No need to waste timeand effort reading or responding to their drivel.
Another old saying to go along with Trembow's: Never argue with an idiot. They'll just drag you down to their level where they can defeat you withtheir superior experience.
