Yeah it's like it's come to a sad end. The forum, the TF2 community, it's all been forgotten and left behind. Very sad, but i still keep in touch with a few who i played with back when TF2 servers were full but obviously life has changed many, things like marriage, kids etc, even emigrating to the other side of the world. And some just stopped gaming. I still play, although nothing like i used to, Overwatch is one that i know a few have moved on to but it's not the same.
I think it would be a good idea to corroborate a list of members and what pc games they play nowadays, maybe even PS4 or XBOX 1, with usernames so we can see who is playing what and perhaps it will re-unite some of us players?
