If enough people are interested in this, I'm tempted to start this tomorrow. I was planning to begin in the Crystal Desert and cap skills in Thirsty River or Elona Reach (Since these two mission have the same skills available. Dunes of Despair also has the same skills but misses out the Warrior elite, so we won't do this in case someone needs to cap it) and Dragon's Lair for our first get-together. Then we can begin to cap skills in the Shiverpeaks and then the Ring of Fire Islands. Of course, if nobody needs any skills in the Crystal Desert we can jump straight to the Shiverpeaks.
Timezones aren't too much of a problem for now, so I was thinking of this every weekend:
Americans: 7pm EST (Saturday)
Brits: Midnight (Saturday)
Aussies: 11am (Sunday)
New Zealand: 1pm (Sunday)
Feel free to suggest other times

As for the skills available, here's a list:
Thirsty River or Elona ReachWarrior: Warrior's Endurance
