I was going to write a full fledged post about this, most possibly one that I would've copied into the FAQ forum, but to my amazement, I found a very excellent flame article which would've said many of the things that i was about to write.

Yes anyone, including Site Administrators can be flamers. Many people think that because the administrators are virtually gods. In a way, they can do whatever they want, but in the end, loosing posting etiquette will cause the rest of the people to loose that posting quality by example.
That's when, I believe, the Staff and people like me come in. We can just persuade the admin to change his posting style a bit, not by flaming back at him or threatening him, but by writting an argumented post concerned to his attention and most possibly, provide some solution.
You can't fear the administrators, because then all you'd be is a spec in a box. You have to respect him, but not be afraid to contradict or write against his thoughts in a civilized manner.
