Users that have “Who can contact me” set to "Only researchers whose message invitations I have approved" as a profile privacy setting, will be asked to confirm, or decline, messaging invitations before being able to reply.
When you receive a new invitation from other researchers, Loop notifies you in 2 ways:
1. Via an email to your primary email address, linked to your Loop account.
2. Via a conversation notification bubble that appears in the bottom right corner of your screen when you log in on Loop. When this is clicked, the conversation panel will slide-in.
