This is basically a general rule for the entire CC section, except contests, but when rating/commenting on a card, please do not be a jerk and flatly tell a user that their cards are less than satisfactory. If you think a card is not of satisfactory caliber, offer suggestions to improve it. Do remember that a few of us are still new to this.
Just don't act like a certain mod on YCM about it (in essence, just don't act high and mighty just because you're one of the cardmaking gods of YCM). Yeah, I'm referring to JoshIcy if you don't know already. I won't go into details about him being one of the best cardmakers on YCM and being a mod of that section. I respect him for that, but I do not appreciate his mentality towards cardmaking, especially towards myself.
If arrogance is your mentality, then I have no objections of banning you from the cardmaking section permanently.
(I know I'm being a little harsh today on the last part, but I don't want another him running around here. So in essence, just be nice and give suggestions to improve.)
