This is a great way of marketing! I like your explanatory approach and the examples that you gave. I hope that many people will download your material. I do hope that you will be able to help people who really need it.

There are so many options online but we sometimes can't make a good use of them. It could be that we're missing some knowledge needed to use them or that we don't know about such options at all. This is why I find posts such as yours very important :)

Have a lovely day and thank you for sharing!
