Recommending a member to a topic in the forum

When I post for example a question about a specific coin and I might know some members who can answer, it would be nice if I have a feature in which I send "invitations" to members to view the question. Even other members can do so (not necessarily the author).
What do you guys say?

Regards,
Omar
