I am using a VF page for my 'Visualforce Tabs' Community Home page. I have a custom button on top of it which says: Instructions Reviewed. Clicking on it would take them to another page. And whenever the user logins again, the button should not be shown at all. How can I achieve this via code?
I think a checkbox on the User record can be used as a flag. As I am an administrator and very new to programming, I am not sure how to achieve this.
