Could Someone Give Clear, Specific Direction As To How To Add A Signature Link

Hello,I've searched the FAQ section and looked at posts throughout the forum, but there really is no clear direction how to add your signature.I have 24 posts and have been a member for more than 10 days...So what am I missing? Even when I go to the section that says "edit signature", there is no editing menu like a hyperlink button that will allow me to add my url. Is there something else that I need to do? Do I need to add more posts? Ask for reputation ( Not sure what that means). When I go to "edit signature" I don't have access to any of the editing features...Also...please tell me how many posts am I allowed daily with my signature link...Please give clear, specific direction on this matter...Thank You,Howard Spinney
