Change Permalink ( remove /blog/ )

Hi guys :slight_smile:
I am using buddypress daily theme. on the subpages its all fine, but on the default home blog i cant change the permalink (cant remove the part /blog/)

Example: right now its:
http://gaming-tools.com/blog/steam-download/
but i want it to be:
http://gaming-tools.com/steam-download/

in the permalink settings this part is predefined
here is a screenshot ( http://gaming-tools.com/wp-content/uploads/permalink.jpg )

Do you know how to change it? :slight_smile:

Thank you!
Kevin
