Add a disclaimer about certifications
On the very first certification in Sakia, it could be very nice to have a warning dialog of confirmation with the following content:
1.) Don't certify an account if you believe the issuers identity might be faked. 2.) Don't certify an account if you believe the issuer already has another certified account. 3.) Don't certify an account if you believe the issuer purposely or carelessly violates rule 1 or 2 (the issuer certifies faked or double accounts)
