Celtic Heroes

I am curious as to how to become a beta tester for new content? Would it mean not ever being able to play Celtic heroes (real app) and only playing the Celtic heroes (beta expansion app). Is there an Application because I feel that I can benefit as a beta tester. Give my input on different things ect ect.

When the next beta begins we'll be opening an application process for anyone who wishes to become a beta tester.

However, please be aware that being a beta tester involves a lot of time and effort and applications should not be lightly made.

lol for me it would be a summertime thing cu of school.
