I wonder if it's possible to make the site with 30 premade accounts for a group of special clients. The thing is I need to know that specific client saw the site. So, for example I need to make about 30 accounts with 30 logins and 30 passwords than I will give one to each client and I want to see who actually logged into the site. Does anybody knows any tool for this? The site will be exported so there is no problem to connect MySQL data base.
