How to Turn Off Signatures
As someone mentioned earlier you can edit your "Display Options" so that signatures don't show up if you're on dial-up or just don't want to have to scroll past them. To eliminate signatures click on "User CP" on the left end of the Tool Bar near the top of each page. Then click on "Edit Options" under "Settings and Options" on the left side of your screen. Then scroll down to "Thread Display Options", click on "Show Signatures" to un-check it and then scroll to the bottom of the screen and click on "Save Changes". Now you won't be bothered by anyone's signature. :) You can also turn off Avatars and Images in the same box.
