Many other websites became available year-round, devoted to Santa and purport to keep tabs on his activities in his workshop. Many of these websites also include email addresses which allow children to send email to Santa. Most of these websites use volunteer living people as "elves" to answer email sent to Santa. However, some websites, such as Santa's page on Microsoft's Windows Live Spaces, have used or still use "bots" to compose and send email replies, with occasional unfortunate results. One particular website called emailSanta.com was created when a 1997 Canada Post strike prevented a man named Alan Kerr (credited as the "Head Elf")'s young niece and nephews from sending their letters to Santa; in a few weeks, over 1,000 emails to Santa were received and had received 1,000 emails a day one year later. Now celebrating close to two decades on-line, emailSanta.com receives roughly 1 million emails a year.
