do you have to have a web site to transfer files for you? theres an easyer way that i use its like Firewire Disk Mode but since macs before 1999 did not have firewire, you can transfer files via ethernet cable. its about as fast as usb to me but it works well. just turn on all sharing on both macs(i suggest disconnecting your macs for the net since file sharing is on) meaning file sharing, web sharing, apple talk, and application sharing. go to TCP/IP look at IP Address and on the iMac click Go near the file and edit area click "connect to server" and type in the ip address on the imac and click connect. it will ask you for a password and user name, type the name of the preforma and password for the preforma, bam your in bizniss.it works great!
