Breaking this off of the overcrowding discussion. The biggest event in Serbule is the Poetry Jam. It's an event that can't be split up, and as server population grows, so will the PJ.
Kaskrim talked about how crowded it was already getting in another thread and suggested making the tavern bigger. What I'd like to see is a door leading to a party room. Make it the basement area. Click on a door, go downstairs, and make it as big as needed. This would give the growing event more room, and relieve some stress on Serbule.
It might even be something to consider for the market in Serbule.
