Wanted to point out that yes, they do follow, you need to train a skill and I think a magic way to get the to follow for longer and more consistantly and many of us had non-functioning pets because we doned the ring while NPC server was down, and Weltall stepped up and did a lot to help figure that bug out and help get the fix implemented! (bug 980) (others may have also worked on it, but Weltall was the one who, when I asked him about it, took the time to actually go investigate it and figure it out while I was chatting to him!
As far as the commands, sounds like you found them. There is a tab ingame with all the commands that really helps figuring that stuff out. I would also expect (though have not verified) that the PSwiki and maybe even deep in this forum would have additional information.
I would start with PSwiki and ingame help options, then if you get stuck, ask a freind ingame (you are making friends, right?

) then if still stuck, search the forums.
It would be nice to have them implemented fully, even if they could only attack the weaker kikiri. (many of you know which kikiri that would not include, eh?

)
But I am just happy to have it follow me now and then!
