Rules to forming a party:

1. Form in Ul'dah--this is where everyone is, and it is where everyone will go to meet up for teleport to camp location.
2. Set your Seeking Invite flag if you do not want to form a group yourself.
3. Use search to find people in your level range. I typically find more people to level with through search then i do through shouts because most people who are playing solo doing leves or quests will stop what they are doing to join an exp group.
