Online users list, and add to firends

it would be good if there was a way we could show all the users that are currently online, like phpBB does on the bottom of the screen.

also, if we could add a user to our friend's list without sending them a email saying to join the site.

If you point me in the right direction I may be able to make it my self I just need to know where your variables are and how to refer to "users"

Something like:-

{if}
({$user} = {$loggedin})
echo ""."{$username}"."
";

{/if}

or something like that to place it in the footer so that it may be on every page

I would love to see this too. In the meantime, I found a free "number of users online" script. If anyone wants it, PM me and I'll send it. I also love the idea of adding friends without having to send the email each time.
