Minato-mun runs the martial arts school and will proooobably be putting up a post about it some time... in the future |D so Zoro could always comment to him if you'd like to get in on the school.

Seifer will definitely be asking for people to volunteer for the Watch so if he thinks Zoro might be partial to that he'll definitely ask :3 Hunting... I'm not sure if he's going to mention that I have to talk to Naja-mun, we'll see |D still if Zoro ever says he's bored or something Seifer's got a list of suggestions of things to do including the hunting squad.
