Really like design #115. But will need a favicon to go with it.
If you think Google (prime colours to show cheekiness), Apple (simple classy apple), Fedex (an arrow between the letter "E" and "X" to give the impression of moving forward, fast), etc.
What we need really is a Favicon together with the design of the words (think Belugapods.com, Yobongo, etc) - something easy to relate too.
