Thanks. That will help a lot.
I think that if we keep seeing problems with individuals causing everyone lots of damage (and they don't quickly fix the mistake as Arx and InsanityIncarnate have done), then they should leave the group. If someone is not doing their dailies and not responding to messages (meaning they probably aren't even visiting the site), then we can remove them from the group.
Anyone who has died due to party damage, I encourage you to undo the damage, since it's not your fault. It's simple to do. In the upper right-hand corner of the page, click settings>site. Then click the button that says "fix character values." Here, you can reset your stats to where they were before you died. I don't consider this cheating because the party system is pretty unbalanced right now. If two members of a party can very easily kill everyone else in a matter of one or two days, something is off there. There should be some party accountability, but the current damage is just too high, and if people keep dying, it will undo all the positive motivation the site is meant to provide.
Part of the problem might also be that this is clearly a high-level quest. I didn't see any indication that any quest is easier or harder than any other when I was looking through them, and just picked rats because hey, it's an RPG, we gotta get the rat quest out of the way. Next time I'll be more careful to take an easier quest.
