I have a macro setup, that has caused people to think I'm being a dbag.

I mark targets

/marking "attack1" <t>
/party Attack <t>!

They see a sentence with ONE capitol in it, AND an exclamation mark and are like 'woah dude, stop yelling at me'

Well every sentence in the English language should start with a capitol. Yes, I'm giving a command, which is what an exclamation mark atually designates. I read up on my fights, so I know what to mark. If I don't, usually one of the 2 whm's I run with will mark stuff. He may not have a chat comment to go with an enemysign, but it's more likely (s)he'll flip on you for not following marked targets.

My macro is really just informative. If people don't follow it, I just try to cope, get threat on the mobs they wake up/disturb etc.
