Posting on behalf of a group in Yammer

I would like to know whether it is possible to post on behalf of a group in Yammer. 

Is it possible to impersonate a user and post on behalf of a user in Yammer. I found this link in the yammer developer section which talks about impersonation but I can't understand it.

Any help on this topic would be really helpful.

Need it to manage senior management accounts.
