Ok, thanks to both of you. Sounds like I'm good because I've never posted an ad hominem ("dropped on your head as a child?") in any forum--even when it is allowed.

I'm still glad I went over the rules because I never would have guessed there was any problem with stuff like "thread necromancy." If anything, people are usually reprimanded for creating new threads instead of reviving old ones (no matter how old) concerning the same topic. I was confused about that too, but there was already discussion about it here which made the reasoning clear to me.

I didn't see any commentary about this other issue ("that's not what I wrote"), however. The reasoning behind it is obvious (unlike thread necromancy), but the nuances are trickier.
