this maybe simple i dont know what it is called and i checked the tutorials and i didnt see anything about it so i wanna know how to make it when someone goes to my site they must login before they can see anything

try usergroups permission

Guest / Not Logged In >>>>>>. can view forums = NO

i did that but it still shows the show box and whats going on and a few other things basically i want it so when you goto the site it automattically directs you to login and all you can see is the login screen and nothing else untill you have logged on
