The agree to rules was added in version 10.11 back in 2012, and I think the quick login was removed at the same time so as to force the user to agree to the rules. WebWiz seems to interpret European and US laws to require this. I'm sure that lawyers can discuss for years whether that is correct or not...
If you know a little HTML, it is very simple to change the accept rules to default to yes. I did that, and while I was at it, I also changed "remember me" to default to no (some users will forget that to uncheck it when they use a public computer). If you like, I can send you the patched file.
