Here's a little guide I wrote on getting your Windows Live / MSN Messenger status to appear in your sig, as I have below ^_^
*Before Starting, make sure you have the latest version of Windows Live Messenger (Formerly known as MSN Messenger) from http://messenger.live.com. Once you have it, follow the below instructions
So you like my signature? Do you also want to show everyone else your Messenger Status? Follow the instructions below
2) Then download the latest version of Mess Labs from http://messlabs.com/download.php. Once downloaded install using the supplied file.
3) Once installed, The login box will appear. Login using the details you supplied on the register page you visited before.
4) Login to Messenger. The MessLabs client will then grab your Display Picture, Display name, status and Personal Message
5) Now for the fun part! Here is where you get to choose the image you see. Head over to http://msig.msgshit.com/. Select "MessLabs" and enter your MessLabs username. Choose your desired status image (I went for the Latest WLM one), then click Submit Form. You will then get some 'bbCode" to put where you want it.
