Thanks for your submissions. I'm sorry but I had to reject entry #6 as it wouldn't give a very "professional" look to the conference, which is one of our goals.
Entry #5 is more interesting, even though at a first glance I'd say it's the cover of an O'Reilly book. Could you please elaborate a bit on it?
Hi Brandan, thanks a lot for the new entries. #24 looks promising, maybe I'd try to keep the logo horizontal, use the php blueish purple either for "php" or "Day" and leave a single flag, if that helps with the overall design.
thanks for your new entries and sorry for the delay in our comments. After a meeting with the other guys, the ranking of #35 decreased a bit. Colours are a bit off and one thing that people didn't like was the overlap w/ negative effect.
