how to add more friendly permanet links?

You can make this changing link menu in admin to /user/home and adding a line in your htaccess. You 'll have to change sitestats link into DB too and maybe some other occurences of the link into php code.

Be careful if you don't don't understand what you do !

You may need to make a 301 redirection too if google has almost referenced you old link (member.php).

Have fun!
