While you're senior and decide to go AFK, what's the amount of time you have to get back and still be senior? I have never seen a specific amount of time that an admin has to return to his or her computer to keep seniority. Other admins claim it's 10 minutes and/or 15 minutes. Regarding my case, I was gone for a little more than 30 minutes.

If anyone can show me where this is written, then I'll greatly appreciate it. Thank you
