I joined on my own, a long time ago. It was for a few specific reasons though:
My net at the time sucked worse than it does now (and that's saying something) and eGO tf2 servers were some of the only ones I could find that didn't automatically kick you if you went over a certain ping (like 100 or 200).
Second reason: Convoy. I fell in love with that server/map, and I played it for a loooong time. That's how I found eGO and that's still my favorite tf2 map.
