@Chris D why not for Xenforo 1.x as Xenforo user i have no idea when Xenforo 2 will come is it this year or next or ... because there is no time frame i can't plan anything for the next-gen. I can only plan for Xenforo 1.x that's why i ask no and not for later on, even if by some fluke Xenforo 2 comes real fast learning how something works now could benefit me later on. I don't believe it would matter if its official or made by third party quality is key in these tutorials and i like how its written there is one unofficial tutorial that i also like it was the explanation how the directory structure works and with the classes was very wel written.
Well there's less chance of XF 2 coming real fast if we stop developing it to start writing tutorials for things that could end up being out of date.
Seems like a third party tutorial is a solution for you. Great. Maybe someone will create one. Or, it might just be easier if you ask a specific question, then you will likely just get a specific answer. This is also a solution.
