If you want to tamper with a bulletin board notice, please inform a DM. Don't type "rips down notice" or emote something along those lines because that doesn't work - everyone can still see the notice. If it's something serious, it can be arranged ingame, we can decide whether or not an NPC "see's" you and reacts accordingly, I know it's hard work, but well, it can be worth the time if things develope because of it, huh?
Conversely, if you write something that would be considered a controversial bulletin wise, try and do it ingame as well as here if you can :)
There's a scribe there for a reason - don't worry about his IC knowledge, we'll consider it OOC.
