This is both a complaint to the GM team and a request to the playerbase.
The Hydlaa billboard has become really cluttered. Sure, people rarely use books now, and prefer to use maps/parchments because they look prettier, and they can be adorned and whatnot. I'm thinking that maybe they are even less resource intensive, I don't know.
Still, I'm asking the GM team to please tidy up the billboards if it's possible, and while I'm at it I'll suggest to you other players that, to allow GMs to know for how long has an advert there, you put, in brackets, the date when you posted it. That way it can be monitored better, and removed if there hasn't been any activity or confirmation by that player that they still want it there.
