I would Live to suggest a new Feature for the BuddyBoss community. As this feature is very crucial for me and I think it will be useful for many more clients for you. You should Integrate the feature for the email invites Like if someone invited by any existing member then it should show on their profile that who was invited by whom. It will help community manager to track you all are coming into community by whom. Otherwise if a community is invite only then a single spam account can bring multiple spam accounts to our community. Also this can be work as a referral feature and members will not bring unnecessary members to the community
