I have the following use-case:  When a user does an action (e.g. send a message to another user) - I want it to appear on the Sender's Journal too.

Facebook has this;  So if I post on other Walls my profile will show the actions I have done:  e.g. Rod commented on this photo, Rod posted on this group etc.

So User A posts "Hi" on User B's profile. Hi appears in the global journal on the home page and in User B's profile. 

But I want User A's profile to show any action that User A has done - e.g. A posted on B, A did this etc. like Facebook does. 

Is this possible?
