Update of Payplans and payment methods in Brazil.

Hello!

I'm very excited to upgrade to Payplans, but I need to ask some questions before doing this:

1- I have small customizations (you did for me), but they are very important, how can I keep them?

2- If I upgrade to a test site (main site copy), can I import the new users and signatures?

3- Is it possible to create the Pagseguro and NET application? In Brazil they are very well known and used.

4- If I resolve to update the payment plans directly on the main site, what current settings can I lose?

I installed it on the test site and it really looks great! I will configure with a paypal account to test and then I will do the PT BR translations.

Thanks again =)
