peter, one of my relatives works for a government dept, there email system does not allow any picture files to be uploaded, wat they do is just change the extension type to suit. so instead of file being *****.jpg they rename it to be *****.doc this way it allows their system to send and recieve all they do is say what extension to change it to after you have downloaded and saved, maybe tis will work for your .xls files. just rename it from boat register.xls to boat register.txt than just tell people to rename it after they download. ??????????? worth a try maybe????
