However ElderShadow,
The information needs to go in your PROFILE.
Click on Profile at the top of the page and put your "sig" info in the Signature box.
And you may have a checkbox for "Enable HTML"
Make sure it is checked.
And make sure that the "Attach Signature" is checked as well.
That is not in the profile that is below the post box when your are replying to a message.
