Scratch

Signatures prety much are used to discribe your personality or advertise a project or gallery. It can be your favorite quote, a link to your awesome project, or maybe be one of your drawings [if its dimentions arent too big]!

But how do you get a signature? Well for one, you have to be a scratcher. Once you reach that ranking, you can edit your signature by clicking profile up at that blue bar under Scratch Forums thing.

To get an IMAGE, you'll need to get the pictures img code. Not the code in your files, a code from a website. But how? Its easy. Some sites will give you a Forum BBcode code
Sites such as Photobucket, imageshack, and plenty more.

Hope this helped, and have a great day.
