Is adding a signature considered spamming? [duplicate]

Question

Possible Duplicates:
Should ‘Hi’, ‘thanks’ and taglines and salutations be removed from posts?
What is the policy on signatures and links in answers for Stack Overflow questions?

I would like to add a signature to all my answers?

I would consider this fair use when I spend time answering questions. The signature would of course contain a link and obviously, yes, it is for improving the page rank.

Answer 1

Signatures are not allowed on Stack Overflow.

Put whatever information you want on your user page -- that's what it is there for! -- but cluttering up questions and answers with redundant information is not a valid use of the system.
