First, the admin has little time these days, especially with the convention coming up. So I apologize for him for any poor communication. I've been given moderator privileges to help him out so I'll try to smooth over what I can.
There was at least one complaint about the "hi" posts that bumped several threads. I saw several in one in a row. This is completely unnecessary, especially if the thread is on the first screen of page 1. Don't do it.
If it was the large avatar thing Luana-neko mentioned, then I suggest that everyone make sure that theirs are within the acceptable range. More than marth have huge avatars and banners. The avatar control panel where you can update your avatar explains the size limitations. Follow them. If you don't understand them, ask - someone will be happy to help you out. Obviously something near half a page is far beyond what is acceptable.
Black Marth, be careful of your guest postings. According to the rules, your IP can be blocked next. Again, I apologize for any poor communication. But please, read the rules, they are short and should be common sense. Don't be abnoxious, annoying, or abusive to others. If you are uncertain if something goes beyond what's acceptable, ask.
