I've used this as my .htaccess file
Code:
RewriteEngine On
RewriteRule ^$ index.php
RewriteRule (^[-_A-Za-z0-9\ ]*$) member.php?&username=$1
and I'm running 3.6.0 and it doesn't seem to work. I then changed member.php?&username=$1 to member.php?&u=$1 but that didn't do the trick. Any ideas, guys.
Is there any explanation on the syntax used for the .htaccess. I'm kind of an .hta noob and I'd like to know what it means, so I can hack it up a bit.

Any good places you guys could recommend as a good guide about hta on the net?
