Guild Wars 2

HI,
Need some help with the guild missions. I have a few questions

1) I know it is limited weekly to 1 chest per week per mission type, but can i represent another guild on the same week to get the chest. For example I did the Guild Bounty in guild A then move to guild B and do guild bounty. Will I get chest for both representation?

2) When is the weekly reset? Is it the same as WvW? Or 1 week after we do the event?

I have another question, once you have unlocked bounties can you do them every 3 days?

Let me help you answer Ace. yes you can do them every 3 days, but you wont get any reward chest.

Anybody can answer my question please?
