Hello Aman, I followed your instructions and was able to scan with the first five sites. The first site that you gave picked up mysearchdial references and eliminated them and I did not see any reference to problems identified on the other scans that I did from the other sites. Site six was not available when I tried it and the remaining sites were a bit confusing for me. I downloaded the site from your link and this seems to have worked. Thank you so very much for your help. G
