Billing Questions

[Beer $lut]

I have never signed up for an MMORPG thing in my life so heres my question. If i were to sign up in the middle of a month when would my time end? At the end of the month or in the middle of the next month? Also if I pay with a credit card does it bind it to it so it keep charging me or do I decide when I want to pay?

I think they are just 30 day accounts.

It doesn't say anything exact but I am pretty sure it is just a 30 day timeline from whenever you start.
