How to share opinions
First and foremost, be sure your opinion is being shared in a proper environment. It will do you no good if you've posted in the wrong place and a moderator or admin comes and locks it.
Secondly, you should check if this sort of thing has been outlined by other users, a moderator or admin, or even IN THE RULES. That would be a good idea.
Thirdly, don't take advantage of the absence of a certain admin to take advantage of those first two rules. (Though you probably didn't know I wasn't around, so you can take this one lightly... I just needed three steps or it would look stupid X\ )
