ClickCash and iFriends offer a non-nude sign-up page, if you are simply looking for a join form without any naughty bits. You can
see it here. To use this page with your ClickCash account, just add &pccacct=YOURACCOUNTCODE (and, obviously, swap out your account code for YOURACCOUNTCODE in the link).
But as for a non-adult webcam area, that's not something that is currently available on iFriends.
