Mk, you submitted 3 great choices. I actually like all 3 but would like to see just a couple more variations. I put entry #36 in first position but still haven't decided which one I like the most. I'll ask some friends for their feedback too.
1. Can you try one with the "S" and "N" the same size as the other letters? I'd like to see the difference.
2. I like the graphics you used in the logo. Any variations changing colors, backrounds, and shapes would be great.
Nice work.
