Pretty simple request—I’m used to being to type /afk in games and have myself flagged as absent; some games even allow you to put a small message such as /afk for bio, /afk letting cat out, /afk on phone. In that case, whoever sends you a tell will get that message back as an explanation for why you’re gone.
I’m absolutely fine with not being able to put in a message, but I would still love to be able to mark myself as away quickly. If not /afk, then /away works as well since it’s also short. Thanks for your consideration!
