Hello Runemy!
If you add users to a SECURITY GROUP (which is what you did - with !adduser <foo> <bar>), you won't see them in the online-list. For people to show up on the online-list, they need to be either member, guest or otherwise in the user-table. If you make them guests, they show up as guests in !online, if you just turn on notifies for them, they will show up as "Other" in !online. Making them member will be pointless as roster-updates will wipe them on org-bots. So either make them guests or just turn on notifies for them. Hope I wasn't too confusing...
