Welcome to the developers section. Glad to see you here.
We do not want to charge for this service, however there is a lot of man power going into the material.
Why do we do it then?
Partially it is blatant self promotion. There might be a situation where you need someone to help out, building your next killer application in Revolution, maybe you even want someone to build it completely for you. Reading tutorials written by us, might help you judging on the quality of our work. But there is a multiverse full of reasons why we do it. Most importantly, we are very fond of our work. Really. We are convinced we are doing cool stuff and we love to show off a bit ;-)
We believe in the power of knowledge. We want a strong community of Revolution coders. We like to help. And we like being helped. We have been using all community channels to learn over the past years and we still learn. We do not take the goodwill of the helpful people on the revolution lists and forums for granted. We must give something back.
Iif you like what you see an want to support us continue our work on this material, we would appreciate if you bought one of our products or made a donation through PAYPAL. You might even considder to sponsor a tutorial.
The tutorials are there to compliment the other material that is available - but they are not a replacement. If you´re just getting started using Revolution or Revolution Media you´ll be able to understand the tutorials, if you have read the basics section first. I recommend that you work through the Resources in RevOnlines Learning center before you start. If you have problems understanding techniques discussed on these sites you might either take a look into the basics section or look up the term in the Revolution/Media Documentation. Everything that is not covered in the basics section should be available in the tutorial itself.
Some of the tutorials we write will require add-ons to revolution. Those may or may not be available for free. It is likely that many will require the use of one or more of our own libraries, like animationEngine. Of course we want to sell it.No need to pretend otherwise. But we do not try to sell you something we wouldn´t use ourselves. We use animationEngine in every single application we develop and also in most of the client work we do. it is a real time saver, but maybe we are showing off again. :-)
Nuff said. Onwards!
