Signature files are a pre-written text file added to the end of an e-mail message or a blog/forum post. They are used as a closing or end to the message. It typically contains the sender's name and address, but may contain any kind of text or link that is repetitively sent. Signature files are under-rated as a way to advertise or promote a product, web site, or affiliate link. Here we will explain how to make one for emails then for a forum/blog.

 The easiest way to add a signature to every e-mail message is to automate it. Most e-mail software allows an automated signature.

Outlook Express  It is very easy to make a plain signature in Outlook Express. You just open Outlook Express, click on Tools/Options/Signatures and follow the prompts.

Then go to the Special menu and choose Switches. Click on Use Signature. Your signature will be appended to all of your e-mail.
