BB,
The problem with canned apps like WAMP is that it’s not very flexible, i.e., using localhost, your foldername(s) MUST be subdirectories of the localhost AND, therefore, cannot be the home page of any site (localhost is the Home directory).
IMHO, learn to use the httpd-vhosts.conf and hosts file (Windows/system32/drivers/etc/hosts) to create virtual domains which are not required to live under localhost.
