I am now on the month to month subscription because I wasn't sure if I would commit for a longer term. Now that I am sure I want to continue, I want to just do a 24 months subscription. How do I do that? Do I just go to add subscription and buy the middle option and click on SIGNUP at the bottom or do I have to stop my current 1 month subscription first then do the above? Will the system figure out that I did a 24 months subscription and automatically stop billing me for each month or I still have to manually stop the 1 month subscription; otherwise I will end up with a double billing =) ?
