# Introduction
|
|
|
|
As the user navigates through the MISP interface, he can sometimes be lost about what to do or not to do on the platform. Noticelist have been created in order to help and guide the user during his use of MISP, by showing several information to him, or giving him easy reminders.
|
|
For instance, due to GDRP, users are expected to be more careful about the information they share, and the GDPR noticelist can be used to help them with this new regulation.
|
|
|
|
MISP noticelist is a public repository of list of notices to show to the user about the information he uses or share.
