WiseStamp is a Firefox Add-on that helps you create a custom email signature filled with links to your other online presences, your IM usernames, and even your latest blog post. As of now it works with AOL Mail, Hotmail, Gmail, and Yahoo! Mail.

After you install it, you just need to set up your signature. You can add almost any information you can think of: images, links to your blog, and phone numbers. You can then select vairous social networking sites that you belong to and add those as well. For example, I added a link to my LinkIn profile, my Flickr photos, my Twitter account, and my Facebook profile. You don’t have to stop there though. You can add your YouTube videos, your Digg profile, your Ebay store, and more. You can also create a signature for business and one for pleasure.

After you’re all through creating your card, you’ll see that the info you added to it will automatically attach to the end of your email. It’s really a simple way to show off your other online profiles with very little effort.
