Helm making a link clickable only once?

[wouyy]

Is there any way to make a link that is can only be clicked once for each user? In a way that, when an user clicks on it and returns to the page where it was, it becomes inactive. Maybe i'm being too vague, but I dont know how could I do this.

Are you using some sort of user login system? If so, you can store their click/no-click status in your users database, and conditionally create the link based on that status. If there is no login involved, then you'll probably need to do something via cookies, realizing that a user could easily delete his cookies if he wants to click it again.
