Dear C. Bischof,

We have been troubled by a problem in our upload engine, which has in some,
fairly rare cases caused information on people to be overwritten by that of
others, causing some identity problems.
We have identified and repaired the cause, and have been able to trace and
correct many of the errors in the information on authors and contacts.
Please, check that for your workshops the information on the reviewers is
still correct. If there is an error, you can choose to delete and recreate the
record, or you can correct the personal information.
In some cases, incorrect author personalities may still exist. Look for
implausible combinations of authors, presenters and contacts.

Please, excuse us for the trouble this may have caused you.

Kind regards,

Dick van Albada
