The game will not be 'opened' for people to start making moves until after the voting is over, which will be at 19:00 GMT on Monday, August 18th. At that point, whoever wins the election portion will be the next Megas and they will then announce when they are ready to open up the save, usually pretty quickly.

On a side note, since you are taking a young avatar that just came of age, it is advisable to stay put in one place until you reach 20 years of age. If you hang out in the capital (Constantinople) you will gain traits which will increase your Law and eventually Tax Collection and Authority traits. If you hang out in a city with a church (other than Constantinople) you will gain traits which will increase your Piety, Morale, and Law, but decrease your Loyalty slightly. Theoretically, you could also hang out in a castle with a Library building, and gain movement points, command, law, and chivalry, but I don't think we have any castles with Libraries yet.
