Type \"/pet\" and you will see a summary of available commands.\"/pet summon\" and \"/pet dismiss\" would be the most important ones.\"/pet name firstname lastname\" or \"/pet name firstname no\" gives them a name you decide.\"/pet follow\" and other actions would only work when the NPC superclient is running.
Yes, that is correct. Some have reported being able to make their pets follow them, but I believe that was quite a while ago. The pet system is still limited, and still very much broken... :}
