Am providing free wifi in a restaurant and there is no need or desire
for the agreement checkbox, can it be removed from the start page as
this is free internet and all this info about payment is going to scare
the hell out of our clients. How do i edit this out and add in some text
simply saying

Free Wifi 30 Min Sessions Clients May Renew As Often As
Needed. We Manage Bandwidth So Even When Crowded Every User Gets The
Best Possible Experience.

I have offered to pay someone for help tweaking the page as this is
all that is needed, otherwise is perfect. If this can be done and
this company does not want to provide paid tweaks is there anyone else
out there who can help me do this if it is possible and acceptable in
the terms of service for this company?

They should have another set of agreement terms for free access maybe
available if not.
