Dynamic Twitter Signature for Emails and Forums
While some folks hate Twitter because it kills productivity, others love to share what they are doing on Twitter. Anyway, Twitter is still well-liked and third party applications like Digsby are making it even easier for people to send/receive tweets.
If you would like to do more with your Tweets and add them as your signature on forum, email messages, then Twitsig is for you. It creates a dynamic image that shows your user image along with your latest tweet. This image can be embedded as signature into email messages or forums where signatures are allowed.

All you need to do is go to twitsig.com and type in your username. Three different embed codes will be generated. One HTML code to embed your signature on any page which allows HTML format (such as blogs and websites), second one in BBcode format to embed the signature on forums. One direct link to the static image, which doesn’t updated when you send a new tweet.
