Thanks very much for your proposal, they are really beautiful and simple.
We have "sinked" the horizontal versions and some of the shaded ones, just to focus on the best four.
#98: The shade on the font makes the name a bit blur, we like more the flat white names.
#98, #101, #102, #104: No comments about the logo, they are almost perfect. But we don't like the selected font (too runic or celtic,
http://en.wikipedia.org/wiki/Runic_alphabet), specially the "K". Can you select ohter kind of fonts? classical but not too sharp?
IMPORTANT: Please the name is not "ebookNation" but "ebookation", remove the "N", :)
