Create an activity diagram for the scenario described below:

A new user registers with the Arena system as an organizer and then uploads a new Connect4 game. Next the organizer announces and organizes a tournament with players. The organizer also solicits advertisers and accepts applications received. Accepted advertisers are then allowed to place their banners during the game. When a tournament ends the organizers announces the results. Make sure to use split and synchronize constructs of activity diagram and organize activities into suitable lanes.
