At the moment I don't expect much traffic but at some point in the future, I can max out the clicks. Say I purchased Tier with 90,000 monthly clicks, I start hitting above 100K. Also, 350K is max. What happens for users who need more clicks? Do I have to upgrade and how would the pricing work?

I'm kind of looking at this tool as something that will be useful (maybe even super-useful) at some point, but I don't know when and how much I will use it, haha. So, I don't want to catch myself with pants down when I'm scaling something and things aren't working or my costs are suddenly high.

Also, I heard a new version is in progress. Are LTD buyers grandfathered into the version 2? Thanks.
