New School - No Constraints - What 2.0 Tools?

Hi All,

I am a recent joiner of the Classroom 2.0 Ning and want to learn from all of you. If you had the opportunity to start a school from scratch, what 2.0 tools would you leverage? I am trying to understand which of the multitude are the 'cream rising to the top'. If there are educational processes that they help improve (like those listed below), make sure to explain what the technology solves or improves. I am also interested to hear about pitfalls regarding their use.

Some areas of interest to me:
- Student/Teacher/Parent collaboration
- Managing the class schedule
- Managing logistics within a school
- Lesson planning and curriculum resources
- Finding prospective students
- Accounts payable & receivable
- Managing the suppliers who provide goods to the school
- Trying to keep in touch with graduates
- Your ideas...???

And note, if someone has already commented about one - please don't feel constrained to tout another or add to why the first was the best... I think we can all benefit from a healthy discussion about Best of Breed Classroom 2.0 solutions!

I feel like a kid in a candy store at the moment and feel that education is finally going to make some headway at changing what I see is still the 1860's red brick schoolhouse philosophy.

Looking forward to reading about your input!

Chris
