Signature question

hello there....when can i include my signature in my posts?

Do not create fake signatures. If you are not yet entitled to having a signature (because you have not been here for 30 days or don't have 30 posts) you are not allowed to create a fake signature, where you post the same text or links at the bottom of every post. Your posts may be edited and you may receive a warning.
