1.Credit: keywords for icons, credit is important. If you are caught not crediting anyone posting icons in this community you will be banned. The only way you don't have to credit is if the user say's otherwise, or has a different method of crediting they prefer.
2. Customizing: Don't customize or modify anything without the users permission. Resizing and adding your username is modifying.
3. Requests: Requests are fine at this community. If you have a picture you would like made into an icon make sure you put the picture behind a cut!
4. Non-Icons: If you want to post a FO Banner, or header, that is fine by me.
5. Advertising: This is okay, but you may only post/advertise your community once, than no more please.
