Is there a way to ask members of your fluther a question?

Sometimes I know one or many individuals in my fluther may be able to effectively answer my question, or I just want the viewpoint of certain individuals on a subject. In the past I’ve sent each of those members a comment asking them to answer my question, but is there a more efficient way to notify them? Can I send a comment to multiple individuals at once? To avoid confusion, my goal isn’t to ask a question to which only those people have access.
