Team management currently can be done only from Infolio web version, in order to manage your team click on Your Team name in the left column, then go to Members section. From there you can see who is in your team, invite new team members, disable existing members and resent invites if for some reason the first invite did not arrive to the recipient. On top of that you can view their status and last activity date. Note, only owner of the account who has set up the team can manage that team.
