Guild Wars 2

Hi,
I started hoarding money in my personal guild, and reached 1k gold, so I decided to withdraw it. Obviously I forget about limits… Now I have questions

A) Is 500g cap summing up gold withdrawn from guild bank and mail, or those are two separated caps?

B) Do all guild tabs (3 separated bank tabs) in one guild share this 500g cap, or each of them has it’s own?

C) Is cap for guild banks account wide so I can’t collect money from 3 different guilds if I reached cap in one of them?

I’d like to know 100% sure answers, thanx ^^

A) It’s 500g from both guild bank and mail combined.
B) The cap is based on how much gold you’ve taken from the mail/guild bank and put into your personal gold amount; the bank tabs have no influence on this.
C) Yes, it’s account wide.
