I will not lie and say that I know what I should study or learn.
If you or any valuable member just guide me that would be awesome.
I did was reading the php manual linked on the above post but felt like lost on the ocean.
But to answer your question I would say, I want to use phpBB inside out and develop MODs for it and design themes for it, so what does it takes?
That is my goal now.
Honestly I was not clear about that goal when I started this thread but after reading since starting this thread I've got my mind set on that goal.
Sorry for my confusion.
