thx for all the helpful input
will remove the javascript redirection within a few days for all of my domains
do you think I should remove it on the main-index-file only (meaning on
www.domainname.tld) or should I remove the redirection on every doorway page as well (meaning
www.domainname.tld/doorway1.htm), that are atm redirected to the main-index-file....?
