There are various ways in which data can be contributed - pick whichever one suits you best:
If you have an ftp server, we can log in and collect the data automatically
You can e-mail the data to us at intervals to suit you
You can post the data to us on CD or on a data stick
We can post a USB data disk to you - this is a really small unit (220g, 11cm x 8cm x 2cm) which takes 1TB of data
