Hi! Sutorcen here. Besides our tutorials there are tons of free resources out there. Well free is not always that simple and not always really free. Don’t know where to start? I’m here to help. After months of testing and using many sites here is a list with the best free resources and information in my humble opinion. The list will be checked for dead links every few weeks and will be updated whenever I find something new and exciting. For friends reading this list I must apologize beforehand if I forgot to mention someone.

Know a cool resource, tool or article then please sent us an email or message on facebook.

Entries with an * at the beginning denote the latest additions to the list.
