Sharing with and organising my family

Hi,

I think we have a common and relatively simple issue that I hope can be resolved with a little guidance from an expert.

We are a small family with a centralised iMac and NAS plus a number of Macbooks.

We have a family account on Mobile Me, we would like to store images, music and videos centrally for all to access. This is the easy bit ensuring that all files are kept on the central iMac.

The difficulty comes when we try to use a main calendar allowing each user to amend, make changes and add to at anytime, we’d also like a family email account that can be accessed and actioned by anyone in the family, additionally we all need private email accounts.

Can this be achieved or do we need a server?

Please help.

Many thanks,

Dave
