if you lurk in the battles and 4chan threads for long enough, you may discover that people are referring to a 'room' that they're in and you aren't. this may lead you to feel excluded from all the fun everyone else must surely be having in that room, whatever it may be.
so i'm here to save you from your misery. the showderp room is an exclusive chatroom on pokemon showdown for showderpians. but i must warn you, it's probably not the climate you're expecting from a room established with that in mind. many of the users of the room don't overlap with people hanging out in the bread or the battles, having fully migrated away from the original purpose of the room. bear that in mind before you type anything in their chat.
the showderp room is an illusory mystery to an outsider. it's sometimes public and sometimes private. the room is called 'showderp,' so if you type "/j showderp" in chat anywhere on pokemon showdown, it'll immediately grant you access if it happens to be open to the public when you attempt to join. however, this isn't always the case. accordingly, simply entering the room once shouldn't be your end goal.
if you can't get in by joining directly, pm someone with room auth and ask to let you in! scotteh, alkanos, and frysinger are all good choices for this.
your end goal should be to acquire "room voice" rank in the room, since that allows you to join even if the room isn't public when you attempt to join. mostly you get this by asking for it, but you have to be a positive contributor in chat and have a base level of understanding of the underlying principles of showderp in order to get approved.
