Tools that will save you time.
I have spent years, creating content for both online teaching and for my own workshops and presentations. I have tried out many tools and platforms. If there is one thing that I know, its that you will get blinded by all the options. One tool that I have consistently come back to is Beacon, E-book creator. I keep coming back because they keep getting better. What's more, it's an Irish company based in Belfast and it will save you time (and money).
