Post on not current user timeline


Hi, I would like to ask if any body knows about possibility from app to tweet to not current user timeline?

Use case scenario:

  1. User logs in to my website using twitter account (via OAuth).
  2. User creates some article
  3. User logs out.
  4. Admin logs in into my website (via webform authentication, not using twitter account).
  5. Admin approves article created in 2 step.
  6. My website tweets “Check out my new article…” on user timeline.
  7. Admin logs out.

Question: is this scenario possible? if so, are there any documentation how to implement it?
