When members interact in the community and contribute content, your community learns about the members and keeps an internal index of their expertize. This is continuously monitored and gets updated with time.

When asking or reading questions, the community can suggest the most relevant members to request an answer from. Once the request is sent, the members get notified that a community member has requested an answer.

This comes handy for both your internal team as well as the community members to collaborate and get trustworthy solutions.
