 ## How to Implement WUPS
 
+**Note:** If you have already enabled _Auto-suspend users after period of inactivity_, you can ignore this section. Otherwise, please read this section carefully.
+
 Implementing WUPS and/or activating REDCap account suspensions can require some careful planning to avoid annoying your users who have not logged in recently.  If you have never used account suspension on your REDCap host, activating it will cause all accounts that have not logged in within the _Period of inactivity_ to be suspended within 24 hours. If those people want their accounts reenabled they will have to ask the REDCap admin to reenable them.  That generates the kind of help desk workload WUPS was designed to _prevent_.
 
 To avoid the chaos of hundreds of accounts getting prematurely suspended, you can run a few SQL queries to adjust the last login dates for your REDCap users.  Done correctly, you can use WUPS to warn these users of the pending suspension, allow interested REDCap users to renew their account, and let the rest suspend normally.
