hi,

On my captive portal page I would like to have a check-box ticked
(so that the user accepts terms and conditions for acceptable usage)
I would like them to HAVE to tick the checkbox - or their login wont
occur (well, it wont even be checked against RADIUS!). what would
be the easiest way to obtain this - is there already something
in the back-end that does this check (some variable I need to pass
as a checkbox item on the logon page?)
