Hi,

First of all thanks a lot for creating this wonderful library. I have tested this library and it serves my requirements well.

I am trying to integrate 2checkout with registration form. I mean on registration page, users are required to choose a plan like free, silver with a fee etc and to accept payment I am using 2checkout. I am not that well versed in CI so I need some direction that how I can integrate feature I want?

Here is the tutorial which uses Ion_auth library:

How can I implement same with flexi auth? I know flexi auth is based on Ion auth but its heavily modified and I can't apply same steps on flexi auth library. This tutorials requires automatic activation to be turned off but I don't see any option in flexi auth to turn off this feature?
