1) Do not edit or use someone else's work unless they have given you permission. If you wish to use it on another site, then ask the creator first. Table coding counts as art as well!
2) Images should be no larger than 650px in width. Your signature area shouldn't look too jarring or have a broken code in it. Signature area's shouldn't be any bigger than 500px wide and 200px tall. This is so all of the images do not stretch the forum.
