Warning - Dummy Alert!!

Quote
Change: When the forum is initially loaded, it will check the HTTP_HOST and protocol being used. By default, if this doesn't match the FULL_URL it will redirect the user. There is an option to force the FULL_URL to the current URL the user is accessing the forum from.
I can't get my head around this. Can someone explain it a little simpler or give an example of what it means. blush
