If I have Imp in play with a virus counter on it, and I access an agenda that I cannot score (for example, it has a Red Herring and I don't have the extra credits), can I use the Imp counter to trash the Agenda? It seems that I should be able to, the way Imp is worded.

Nevermind. I found the ruling over at BoardGameGeek. THe answer is yes, for anyone curious. More on Imp can be found at http://www.boardgamegeek.com/thread/910934/official-answer-about-imp
