Hi,
I'm working recently on many Typo3 Projects and I'd like to have a good tutorial/reference to work my way up. I'm looking for something like Agile Web Development with Rails but for Typo3 if you like. The documentation of Typo3 is good but not incredible so I was wondering if there was a better option out there.
Unfortunately there aren't a whole lot of TYPO3 books available; the only publisher I know of who have put any effort into them is Packt, who have a few:
I don't own them so I can't testify to their quality, unfortunately. But since they're the only game in town I suppose that doesn't really matter that much :-D
Generally speaking, the best resource for learning TYPO3 outside the documentation is probably the TYPO3 mailing lists; I often find answers to questions just by searching the archives. TYPO3-English is for English-speaking general users; TYPO3-dev is for extension developers and those who want to hack on TYPO3 itself.
