I'm in currently with gmail but have found it's a lot of fuss to save my emails, I was told to use something like outlook express in instead but as I don't have the net on and use the schools computers it's a little hard to install a program on every PC just to check my mail. Does any one know of a free email site where ican at least download my messages to my flash drive?

You could install a portable email app on your flash drive. PortableApps.com has a great toolkit of apps that run from flash drive with no client PC install necessary. This would allow you to configure Mozilla's portable Thunderbird email app to pick up your pop3 email.

I like to use gmail. Just to save emails and stuff, I have created a set of folders, and set parameters so that certain emails automatically go to certain folders. Furthermore I have changed the entire theme and layout, integrated the calender, and a whole bunch of other stuff to make it more useful.
