Hello, i have just set up a website, and want to protect the site using login and password protection. Can anyone give me some PHP scripts which will keep a track of usernames and passwords, and add them to the access rights list. is this possible? If so, i would be much obliged if you would do so.Thank you. P.S If anyone needs assistance with HTML, that is my speciality, so send me a message. Always happy to help
