Exciting (I think) new feature in 2.05: Multi group (2x4, 3x5...) support:

with the option to limit invite to a set max party size. eg. 4 so a 8box can be 2x4; if you have 12 and set max to 4 you will have 3 groups of 4 (1-4, 5-8, 9-12) automatically at login,

Configure with /dbox c or /dbox partymax N (make sure to broadcast)

If you are 15 boxing and unset autoRaid, you'll end up with 3 parties of 5, etc...

(works for any party size 2 to 5)
