Having previously used Headway when I saw it as an Appsumo deal I leapt at it. Here is where it gets better: I was able to connect to my previous account (used the same email address) and viola - all my previous content is there.
I'd have been just as happy to start afresh - is how valuable Headway has been in the past. So why did I stop you ask? I took a break to see how much I missed it. I did. Now I've got it for life. So happy. Thank you Appsumo. Thank you Headway!
