The reason im making this changes its because I discovered that sometimes more than 3 people are using the same username and passwors, when its suppose to be a personal acount...what Im trying to do its to check if a username is log on at the same time from two different computers, that way I can make the username and password really personal...

If someone has a suggestion Im all ears...here was my plan:

1. Let each username to acces from two different computers(not at the same time, something like from work and at the house). I was thinkin to acomplish this by setting up cookies.
2. Save in a log when a member logs in. Everytime someone tries to log in, it checks the log and sees if that username its not already logged on. In case it is then denies access.

That was the plan. Im using .htpassword and .htacces, Im running out of ideas, so if someone could help me it would be great... 2.
