Javascript Title change

You need custom scripts enabled.

top.document.title = "Intranet";
function titleChange() {
    if(!top.noodle || !top.noodle.core || !top.noodle.core.title){
        setTimeout("titleChange();", 1000);
        return;
    }
    top.noodle.core.title="Intranet";
    top.document.title = top.noodle.core.title;
}
setTimeout("titleChange();", 1000);

This is an example only; if you want to change the title please use "System Tools > Settings > Theme"
