Glad to hear. :] Feel free to use them or not as much as you like. If you do use 'em, you should credit the original photographer whose photo I used.

You've got to go to your member page, and hit the "Edit" button next to your name from there. There's a text box titled "Signature" to get/update your sig. So you just need the sig picture's url surrounded by the image tags, on that one.

There's an "Upload New Avatar" tool/bit just above the Signature text box. For that, you need to upload an actual file. So you'll have to save the avatar picture I posted on your own computer (make sure it saves it as a .png file), and upload it there.

I'm not sure how tech/RPG-savvy you are. If you're confused on some points, I can explain more. :]
