Site-wide integration

[paulmjno]

Hello,

I am moving from phpBB to vB, which I just purchased. I had a script for my phpBB which allowed me to display user information on any page on my website, and allowed users to login on any page of my website. With this script I could write my own little scripts, like:

if (user is logged in) {
do this
} else {
do this
}

The script also allowed me to retreive the users name if they were logged on. Does anything like this exist for vB?

Thank you.
