Worldspy99,
You responded in August and tried your solution. I simply cannot locate the "Edit Signature" still. I have been lazy ever since but finally I decided to reply to you.
I am using Windows 8.1 Internet Explorer. On the top right of the screen are 3 icons: search, my avatar, and a drop down menu. When I click on my avatar, I get the following options: (1) Manage Profile (2) Forum Settings (3) Log Out. Options 1 & 2 direct me to the same screen: "Manage Your Account". HERE, I can change my name, password, bio, main device, location, etc but NO fields pertaining to add/edit/delete a signature.
The third icon from the top of the screen, as mentioned above, is a drop down menu. This menu simply contains links for the WPCentral site (ex: store, news, etc).
I must be missing something here because it shouldn't be this hard yah? ;-]
