You can post through an ECN after hours on any exchange I believe. For instance one can post a bid/offer through Instinet (not sure if thats still around) or ARCA. There has been so many changes since I stopped trading 3 years ago but I think it all may show up as NASDAQ on the quote box we all look at.

Lets say someone didnt finish a buy or sell order during market hours. That person could post a order on one of the electronic exchanges and if he found someone else to trade with, they can execute the order even though the market is closed. Type up SPY and you will see pre and after market trades all the time.

For level two watchers you will notice NASDAQ will mostly shadow AMEX. It is easy for traders to use ECNS (nasdaq) than route through AMEX, you get faster fills for one. In fast moving markets your fills may not be excatly where you want them with AMEX, specialists have the ability to hold the order and you're at his mercy. If you use ECN's you take stock using limit orders, basically fill or kill orders.

T next to time and sales mean delayed. After hours prints get t stamped.

Someone trading after hours is just really trying to get out or in a position. Not enough shares traded to make me think to much about it though.

All in all it just means more and more people are watching the stock.
