Even though I sold my Seamaster a while ago, I've been updating the card for each new year for people to use & enjoy. Here's the card for 2012 which I posted back in January (page 71 of this thread):
The card is "self-serve". Just right click & save it on your hard drive (computer). To add it as a signature, log in to WUS & go to "Settings". Under "My Settings", click on "Edit Signature". There you can add it as your signature either by just pasting it into the dialog box, uploading it from an image hosting site or directly from your hard drive. I just now added it to my signature below by just pasting the image in the "Edit Signature" dialog box. Easy!
Have fun & welcome to all the new members!!!
