I found this quote on EBenifits.
"Claims for VA compensation, pension and vocational rehabilitation and employment benefits (VA Form 21-526, 21-686c, 21-4138, and 28-1900): A signature is not required in most cases when completing these forms. Prior to final submission of your application in VONAPP, you will be prompted to certify that all information you have entered on your form is accurate. Your certification serves as your signature."
That covers the signature part.
I have to file an appeal soon.........Think I'll take a shot at it because I have time enough to come back and verify what happened.
