*Shakes head in disbelief* ...No you can't until you are an ESTABLISHED MEMBER, which is never going to happen unless you learn to read.
Not sure if I'm right, but I think there's still a way out for the OP. Some folks offer their signatures for sale. Maybe the OP can contact them and use their sig, obviously for whatever the fee involved.
You need to be an established member of this forum to add signature. Keep posting good answers and gain at least 3 likes, after that you will be able to add the signature.
