Thank you for using our service Cure.
We have to, unfortunately, inform you that "Guest Book" feature will be closed on Sep. 30th this year.
Guest Book, the feature to leave comments on profile, will be completely closed and all data will be deleted on the very day of its closure.
You will have to back up the data by yourself if necessary.
We apologize for your inconvenience.
We, however, won't let you down because this is part of improving our service.
Don't be disappointed too much!
