I'm trying this right now. Here's what I got in the template,
Code:
/usercp.php?action=do_editlists&my_post_key={$mybb->post_code}&manage=buddy&delete=*
where * is all user id's, but * obviously won't work. I think a small php script is needed to select every user id in the database and apply it to an array. So it would become,
Code:
/usercp.php?action=do_editlists&my_post_key={$mybb->post_code}&manage=buddy&delete={$userids}
where {$userids} is all existing id's.
This certainly is optimal, anyone got any advice here? Seems this is too much work for such a minor "issue".
