Please register as a user so that I can trace usage of the system,
and mail you if I find bugs. If you have already registered just give
your e-mail address to log in. The service is also available
anonymously, but some
features (notably the ability to define your own indices, to upload
your own data and to use large datasets) are then disabled. As a registered user many forms remember their settings for a few days.
