You can work with coworkers on Log Notes, Petitions, and more using Success Hub's "Chatter" function.
To communicate with a specific employee:
Type "@" in the "Post" area, then start entering their name. Let the autocomplete feature locate them. Type your message after that, and when you click "Post," a message with a link to the record you posted from will be sent to them.
Peer Advisors can receive Chatters messages by switching the "To" setting from "UCSB Only" to "All with access" in the bottom left of the Post window. Please be aware that if this option is used on a petition, the petition's specified student will also be able to view the message in the future.
