How to get amaya logged in to host

New user alert!

I'm attempting to run amaya on windowsXP pro.  It installed without
error. 

Looking over the interface and help menu I see no information to guide
me as to how to get amaya logged into a site where I might want to
edit something.   

It must be a common thing to do but I see nothing in the help menu
that looks like it might tell how.
