My apologies for not being more specific.
Here is how it works now. A student clicks on my classroom and is taken to my homepage. If they choose to enter the chat they click on a url link on my homepage. They are directed to a url page which asks them to sign in. The sign in then loads the chat. What I need is to have a pop up that immediately shows that log in url page in the pop up window. I have a script that currently opens a new window of a page that I created with the url link on it. That is great except the student still has to click that link to be taken to the chat log-in url, which most don't do. I know, the thought is hey, if they don't click on the link to login, what will make them actually put their info into the log in page instead, i'm skipping only one step right? Well....forget logic here, this is administration and they don't use it, they just want stuff and hold the peopns accountable when it isn't done verbatim.
So, I need the code to open a window immediately upon entering my homepage, and that window will be the url page which allows a student to enter their log-in information.
This would be simnilar to say, going to my homepage and immediately a new window with the historychannel.com opening up for them.
