Note: the `Email' below must be a valid email address. It is used as a key into the database as well as a contact address. When the database entries are displayed, the address is slightly obfuscated (`@' is replaced by `at' and `.' is replaced by `dot') to prevent spammers from harvesting the addresses, but this obfuscated address must not be used as a key. Also make sure that you always use the same address when modifying the personal information or uploading your talk.
