Signatures contain information that you want to include at the bottom of all your posts. This might include information about yourself and a link to your personal website (to show people more about yourself or connect), a favorite quote or any personal message.
You can set your signature on your Personal Details page
Our rules apply to signatures in the same way that they apply to posts
Keep your signature within reason. No large text, bright colors or signatures that contain more than 5 lines of text
