OK, this is going to sound dumb but ... I'm afraid I have to ask anyway

I forgot how much space and bandwidth I had. I signed up for the BOGO promotion Power plan back in June I think it was. So I have a few questions...
1. What was the old Power plan?
2. Can I upgrade?
3. If I upgrade do I lose my BOGO?

So now I would have to pay for 2 separate plans?
