You need to register with the RePEc Author Service and you need to have at least one work listed one your profile. You will then automatically receive a mailing in the first week on each month.
No. We do not change the address, you do. Do this by changing the registration email. Log into the RePEc Author Service, and change the email address under "contact".
See all the details at LogEc.
The data collected by RePEc, including the author data, is used by several so-called web services. They display the information about you and your works in deifferent ways. We consider it a healthy competition, and you have the freedom to use the one you prefer on your homepage or email signature.
We prefer that you get regular reminders of your profile in RePEc so that you can update it. But if you do not want to get the monthly emails anymore, you can either delete your registration (log in and look for the "delete" link in the main menu), which makes us very sad, or ask by return email to be put on a "do-not-call" list. You will still get an email when there are major developments, though, or when we think new works of your have been added to RePEc.
