A very important feature in Story of Seasons: Pioneers of Olive Town is the bulletin board. It will be important from the very start of the game, so knowing where to find it is vital.
The Bulletin Board can be found in the Town Hall, which is located at the top of the public square. Go in the main doors and then all the way to the back of the first room to find it.
The Bulletin Board can have numerous different types of bulletins, but the most common one will from people in the town who are looking for specific items. If you can find the item, they will reward you handsomely with some gold, and this can really be a difference maker in the early days of your farm.
Checking the Bulletin Board each morning and filling the request could be worth anywhere from 200 to 600 Gold, and will always be worth more than the sale price of whatever item is requested.
The second type of bulletins are town requests that are placed by the Mayor. These will improve the town in some way, and will normally nudge the player toward exploring new mechanics in the game. These can be worth large sums of gold, netting up to 2000 Gold upon completion.
While there will always be three different Town Requests whenever the Mayor makes them, you only need to fulfill one of them, and can also only claim the rewards for one of them. This gives you an option about which one to complete, as you may not have access to some of the required resources.
