XCess I'm delighted you are thinking of writing a tutorial and I hope you do it. However, before you do, allow me to put on my Editors Depot Admin hat and make a couple of requests.
Firstly, don't reinvent the wheel. If you're writing a tute don't just cover the same ground as other tutorials already cover. Make it new - there are acres of OFP editing where there are no tutorials at all.
Secondly, if you do want to reinvent the wheel, do it properly. Study all the existing relevant tutorials, identify what is good, what is bad, where the overlaps are and where the gaps are. Then write a comprehensive guide that covers everything. Your new tute should be miles better than not only all of the existing ones, but all of the existing ones put together. Yours should make all the others totally obsolete.
Always include demos and examples as appropriate. A demo mission is frequently of as much benefit as the tute itself. Check the grammar and spelling and post it on the Resources Beta testing board before submitting it to the Ed Depot.
Thank you.
Edit: I posted this elsewhere first then saw this thread. IIRC correctly we have nothing on cinematography so that would be brilliant. snYpir and messiah covered the basics pretty well and I don't think there is much need to cover that ground again.
If you want to write a tute, just write it. The people who will most appreciate it have not yet even discovered this board, or even OFPEC.
