We wanted to help clarify the Picking Up the Past surveys. They will be going out at 12:00 p.m. PDT / 3:00 p.m. EDT.
You must collect the survey on a daily basis as they do not stack. You can collect it anytime after the survey goes live (which gives you about 24 hours). You can also only claim them once per server. So make sure you collect them on the correct character.
