Commendations?

[Zipster]

Please note that commendations can only be made by those who joined a duty on their own, and not those in a party.

Is it valid to say that the commendation window will not appear for those ppl who are in a pre-formed party prior to entering the duty?
The reason I ask this, as I ran a DR Low lvl last night, Haukke Manor, and everyone wanted to give me commendations at the end. I received one successfully from one of the people in the dungeon party; however, for the other two (DPS and healer), the commendation window never appeared for them, only the final loot window.

I believe even if the commendation window is dismissed and you haven't selected a person yet, that you can still click on the notice to bring the window back up?

If not, how would you force the window to appear again? Has this happened to anyone yet? Thank you!
