Under My Profile on the left hand side, users that have access to Needs in the Member Area, will have a “Needs” option in the sidebar.
When they click on this, they will see the list of Need Types that are created under Settings -> Needs -> Need Types
To subscribe to a need type, simply click the “Enable” checkbox to subscribe.
When subscribed to a particular need type, when a new need is created of that type, subscribed members will receive an email alert of that need being created.
