The Inn is where you go to socialize with other farmers. To get to it, click on the Map icon in your toolbar. From there a screen will pop up with The Inn icon. You can select your Language from this screen as well. Click on the icon to be taken to the The Inn. The Inn is not a place to get hired to work on other's farms, so do not ask people to hire you!!!
Once you arrive at The Inn, you will see a pop-up screen with two options. If you are looking for work, you will be taken to the Marketplace. If you chose to "drink water", then you will remain at The Inn.
