Creating player events is simple. Go to events, create event, choose the option to play a game and post the event.

However, there are certain details you'll need to fill out for the enjoyment of other players.

1. Begin the event title with your region.
2. State gamemode.
3. Give a time slot, dependant on your timezone. That way a new event can be created when you disband the party, and it won't happen without warning.
4. Expect a flood of players to add you. This is the easiest way for people to join your party.
5. Do not spam events. Doing this too many times will result in a ban.

Example:
[EU] Hardpoint 14:00-16:00 GMT

Now that's out the way, enjoy the group.
