Can anyone help? Ive looked at a ton of tutorial all saying the same thing but i just cant it to work!

I want so you try to enter your password in the usual way, but clicking cancel or getting it wrong 3 times will send you to the join page.

Do you put the htaccess file in the members protected folder? This is what i have:

ErrorDocument 401 /join.html
Is it definatly a 401 or would it be forbidden?

htaccess works on the server, i wonder can error docs be turned off? But 404 ones work?
