Hi! Although this site is available over HTTPS (https://w3schools.invisionzone.com) I notice that many site links I follow (e.g. "sign in" and "create new topic") open pages over HTTP. This is especially problematic for sigh-in form which means that user credentials will be sent to the server over insecure connection. Firefox gives an appropriate warning in such a case. Please fix this ASAP. -- rpr.
