Membership directory software that in minutes lets an organization build its own dynamic mobile member directory. The directory, which is restricted to an organization and its members, includes push notification, interests search, and instant messaging.The Involved Members member directory software represents the next generation of member directories by enabling an organization to easily create a private mobile member directory app that also incorporates interests-based search and instant messaging. In essence, the directory is transformed from passive to dynamic by enabling member-to-member communication based on shared interests. An organization creates a unique interests menu relevant to the organization and its members. For example, a synagogue can create choices that enable members to find last minute Minyan participants. A church can let congregants know about special events. A sports club can create choices that enables members to find playing partners. The possibilities are limitless.
