No problem if your reader is not a recent one ! And there is no deadline for this, it's an open offer
I'm actually looking for articles on all kind of ebook reading devices, if somebody wants to make an article on a cell phone on which it's possible and more or less comfortable to read ebooks, it will be great as well !
The main answer I always get when I ask my readers or other people if they like reading free novels in pdf format is : "I would prefer a real book, because it's tiring to read on the screen and I don't always have my computer with me. You can bring a real book everywhere".
I'd like to show them that there is a bunch of other solutions. A friend of mine actually read my whole book (a bit more than 100'000 words) on her cell phone...
