Frontend question

I have a block showing member photos on the main page, i need to set it up, to show random memebers, not newest? Any help appreciated  :)

I think you need the search into /templates/base/bxbaseindex.php

search for: 

function getBlockCode_Members() {

on line 388

Thanx

there is no such file in /public_html/templates/base

/templates/base/scripts/bxbaseindex.php

in 2nd function getBlockCode_Members

change:

$mode = 'last';

to:

$mode = 'rand';

but how can I create a second block in which will be displaied online persons.. a separated block please
