Oh I just figured out how to read your message. Forgive me, I am new to Logo Tournament! #17 is my favourite thus far. I love the Yin/Yang symbol! Can the COFY be in a slightly thinner font and make the colour a lighter shade of blue with maybe some 3D effect (if this is possbile). Also could you try a a couple of variations of colour on the Communication Online For You (for example have Communications blue, Online green and For You blue. Also do you think the tag line colour could be blue or green? Or would this a bit too much blue and green? What about having the tag line colour as 80% black?
#26. I love this one as well but don't like the Y in COFY (it is just not clear enough that it is a Y). Would also like to keep "Communications Online For You" on the same line.
#28 I like it! Could you please try the font you used for COFY from #9 in place of this one? Keep the font you have used for the other words in this logo please.
