Let's take night kik as the example build and lynxkik as the retheme.

User blacklisted from lynxkik:

Aweee man what do I do ?

Solution: Lynxkik is 3.fuckyou nightkik package name.

Step one: log into night 3.pi (not 3.fuckyou).

Step two: install lynxkik. This will over lap the 3.pi already logged in account with the new lynxkik.
