I like entry 5. It is very professional looking and sperates from the other too cute acadmeic sites. Our customer is going to be 6th through 12th grade science teachers and we want them to feel our services/prodcuts stand apart from what they are use to seeing in the academic space. That being said, if we could add some graphic element to entry 5, but not a person type image like in entry 6. Maybe somethign abstract like saying online, technology or cloud based. Thank you for your efforts.
