No problem
I wish I could get paid for writing these at a desk job I'd get loads.
I'm the sort of guy that plays a computer game and records it to VHS and plays it back to write a full guide. I just like teaching others!
One thing, though. You should develop (or get somebody else to do it for you

) into possibly the existing control panel - access to the tutorials. If I wanted to edit them / upload a newer version, I just go to control panel.
Why do they not appear in the submit tutorials section? I have noticed a formatting error in the .htaccess article which only needs entering 4 characters then viola.
