I thought I would get a quicker answer here. I just purchased a 12 month gold account. I have 2 weeks, 5 days left on my old one.

If I add my new one will it start after my old one expires? Or will it start today?

I am pretty sure it adds on. So if you have 5 days and you activate a 12 month ga, you have 12 month and 5 days of ga.

yep, the time accumulates so you will have 12 months, 2 weeks, and 5 days if you activate it now.

I buy in six month chunks and can add that this is my experience too-it adds on.
