In Community site, users can Join automatically as I have enabled Auto Join. But before join, I want the user to be directed to a page where a Disclaimer statement is displayed and they need to Agree to the Disclaimer statement and then Joined automatically. if Disclaimer is Disagreed then the user should not be allowed to Join. In either way I also need to log the user's network ID for those who Agree/Disagree.
Please advise on a best possible approach preferably using client side code. Thanks in advance.
