If you would like to send us files, please ftp to our anonymous account:
iona.cryst.bbk.ac.uk(i.e. use "anonymous" as the account I.D.), where the files may be deposited in the directory "upload".
You must then tell us the names of the files (mail pps2@mail.cryst.bbk.ac.uk); this is because (for security reasons) it is not possible to list the contents of this directory.
