To change your forum nickname, go to your profile>>Account Related Settings>>Name. Type in what you want people to see your name as. To add a picture to your profile, go to your profile>>Forum Profile Information>>then either upload your photo or specify your avatar by URL. You can also add words to your avatar by typing into "personal text." To change your signature, go to the Forum Profile Information, and scroll down to where it says "Signature." If you'd like to add a picture in your signature, you can copy the URL code and paste it into the blank box. (If you have a picture in your computer, that doesn't enable you to copy the url, you can upload the picture to someplace like TinyPic or Photobucket, copy the URL, and paste it into your signature.) Be sure to type in your password and save your settings if you want to save the changes to your account. Hope this clears everything up. c:
