All servers (with the current exception of OCRP) have been updated with a new report system. All /reports are global and will be displayed to all currently online administrators. So if you need an admin, all you have to do is /report <message> and it will be sent to any and all online admins.
When using /report you MUST give the REASON why you need an admin. Just saying "admin to me" will NOT get you an admin. Admins can reply to you from any server if needed.
Unlike /global, this is an in-line chat system, not requiring the need of a second shoutbox.
