TCAS working nicely!

Hey everyone and PMDG,Today I had my first TCAS "traffic traffic" warning signal. It was totally cool, today in the middle of the day, not really many pilots online on VATSIM, I took a flight from Heathrow towards Manchester, UK, and so happened that me and this dude were flying almost the same FLs. I was FL100, and when he was reaching me, he was in the climb, and we were both on the same airway. Although, before there could even be resolution, I was already heading another direction. But I didn't notice him before the TCAS warned me, which was really awesome...Great stuff!
