Book Lair discussion

So I finally signed up to Edelweiss! I posted about it here: https://anaslair.wordpress.com/2017/0...

I was wondering if any of you guys use it and, if so, if you could give me some tips, maybe there's stuff I have missed and that it would be useful to know.

Have you actually got a book from them? What was the format?
I have read somewhere in the site about DRC, I am assuming the D stands for digital but all the stuff I have seen for review seems to be in paperback or hardback. Coincidence?

I've never even heard of it. When I saw this thread I thought it had something to do with The Sound of Music.
