According to an amendment of the Communication Network Act, a member is automatically withdrawn from membership two years after membership registration, if the member fails to reconfirm a request to verify the membership.

After the automatic withdrawal, the user's ID will not be found using "ID Search." In such a case, you have to re-register on the website for membership.

For membership registration, click the [JOIN] menu at the top of the web site, and follow the guidelines for Agreement to the Terms and Member Information Input, etc.

- Membership registration is allowed just one time.

- Most of the search functions can be used conveniently without membership registration.

- The membership is maintained only if the member reconfirms the request for the collection of personal information every two years.

- The membership is automatically withdrawn if the member fails to reconfirm the request to verify membership.
