How do I put a favicon? And how do I make the forum that only registered users can see anything?

In the root directory of your forum, just add a 16x16 icon there and make sure it is named "favicon.ico" .ico is the file extension, you just can't rename an extension, you can use this tool to change the image format properly.

The best way would be to upload your favicon.ico image in the root of your server, inside the www or public_html folder. About your second question, it can be done at Admin Panel->Features and Options->Allow guests to browse the forum, uncheck it.

Bookmark the page, then close your browser and reopen it and open the bookmark. It's working for me, I guess. I see something with two swords?
