is there a plugin or something that I can set more than one password for a page or a post?, in the dashboard when I write I post or a page, there is a option to protect it with password, is there something I can use, or maybe should type? example: using the ";" or ":" or "," or something like that?.. anybody knows a plugin or somethin for that? oh and I am talking about multiple passwords as options, they can either use password1 or password2 or password3 etc etc...
