ok, first suggestion, it seems to work fine but you need to allow HTML and PHP so that we can make reference to usernames and link back if you know what I mean.
Here is what i tried to make which will be normal for any users to do is to aprove the new fried request so that they both become new friends.

<a href="profile.php?$session[sessionurl]do=addlist&userlist=buddy&u=$userinfo[userid]">Approve $userinfo[username] as your friend!</a>
