phpBB3 Developing - Where to start?

Question

I'm trying to start building a whole application using phpBB3 user system as a base using CodeIgniter framework. However before starting I would like to hear a piece of advice from any phpBB3 Developer out there.

I've been developing for Wordpress and Drupal. But recently I decided I would build up something fit to my needs instead of using a premade application.

The application is going to include:

• Article System
• Video Streaming
• Wiki
• User editable Profiles
• and much more

To any phpBB3 Developer :

• Where to start?
• Any recommendation you could give me?
• Any tips?

Answer 1

I've only used phpBB3 as a forum system, but you should definitely check out the phpBB Development Wiki, particularly the API section.

It has all sorts of neat things, like how to add custom pages and use phpBB's permission system.
