Look, folks.
We don't have a lot of rules here. One of them -- maybe the biggest -- can probably be summed up as "don't be a jerk." Only 'jerk' may not be the word I'd use. Now, how many folks think they may have already violated this rule in a darned short thread?
If someone's grammar is bad, ignore the thread, or ignore the person, or try to figure out what they mean and then answer politely anyways. If you think someone is rude to you, report the post (little exclamation point to the left of every post) instead of being rude back. And for crying out loud, if you want to know about something obscure, please tell other people where to find it and what it is. That's a good tactic if you're asking for help or information.
Okay? Okay.
Carry on.
