Has almost never worked out for me. They either don't give a crap about a challenge I'm looking to do, leave while I'm trying to find more people, or have no idea what the hell they're doing. The solution outlined in the post fixes all of that: * You can search for people specifically looking to do that week's challenge. * You can search for experienced players only. * All the searching is done automatically, so there's no waiting around for the party leader to get the last two people.
