hi
sorry for delayed reply.
You can put it in your theme or just create bp-custom.php in your wp-content/plugins and put the above code.
I am posting it on pastebin for you(the forum post ate my code ).

It will work if you are using the buddypress default theme or a theme which supports buddypress standard theme action.
Please let us know if you are using bp-default or not.

Thanks
