i don't think it's up to you there ar efree tutorials here download them and have a look. At the end of the day this is a business and kev and david's income and don't you think it's nice to not have any annoying ads popping up all over the place!!
And you get what you pay for and so you're getting high quality tutes at a very reasonable price.
