What are the Maccentral Signatures?
I have been a member of the forums at maccentral.com for the past few years. Like most forums you are given the option to include a graphic at the end of your posts, in the same fashion as a signature on a business letter. The difference is i change them every day.

Why do you change them every day?
In the same way that a jogger needs a few stretches in the morning before they barrel out the door, i use the signatures to throw around graphic ideas, colour combinations, or any fluffy concept i'm not sure about.
Most of the time the ideas stay in the signature, but every so often a project gets a helping hand from an effect or a wordplay i think worked well. Ideas are ideas.

Any examples to look at?
You can take your pick from below. The pages themselves are quite graphic heavy.
