We get lots of questions regarding Signatures, Avatars and Profile Pictures so:

Signatures are available to all registered members. They appear at the bottom of each of your posts. They should not be larger than 500 x 100. Also, sigs should not exceed 7 lines if no picture is used. If a picture is used, please limit the text lines to 4. One "userbar" counts as one line.

Avatars are available only to Premium Members. Some older members that do not have premium membership still have avatars as they were grandfathered in when the rule was updated. Your avatar appears to the left of each of your posts and in your profile page. Sometimes it is necessary to reduce the size of your image for it to be accepted as your Avatar. Try 100 x 100.

Profile Pictures are available only to Premium Members. This photo will appear on your Profile Page and can be viewed by other members when they look at your profile page.

You can set and change your signature, avatar and profile picture in the User Control Panel. To access the User Control Panel click "User CP" in the orange bar at the top of the screen. Then under "Your Control Panel" simply select:

'Edit Signature'

'Edit Avatar'

'Edit Profile Picture'
