Multiple people on one login??

I am experiencing security issues on my site. I discovered by accident that two people can be logged into the board at the same time under one username and password and post at the same time... is this a bug? Is there a way to stop that from happening?

you would have to write your own query statement for this one..

If You Know Php or mysql you could create a die  statement that would say sorry you are already logged in

Why is this a security issue? It is normal that you can login a 2nd time (for example with a 2nd browser or from a 2nd pc). I do this sometimes, for example to check the browser compatibility of my website.
