I'm planning to study the xenforo code so I can write a plugin for it. Here are some of my questions:
1) What version of zend framework xenforo used? is it zend framework 1 or 2?
2) If it is 1, are xenforo planning to migrate it to 2 soon?
3) Im not familiar with zend framework for now, Do I really need to become an expert in zend so I can easily write xenforo plugin?
Do you have an advice in writing xenforo plugin?
