I enjoyed the free e-book you wrote, I often use it as a reference when I try to explain cosmetics functions to friends and family. I've kept it on my desktop (computer), but I have accidentally erased it recently. I tried to download a new copy, but couldn't since I'm already "registered" somewhere. It' a bummer. People misplace and erase things all the time. And we expect to be able to download free stuff more than once. Especially when we are not warned that this is a one-time opportunity :wink: Is it possible to fix this somehow?
