100% agree you can't replace people. You get new ones, and they're not the same. But then, they also do or say things the old ones never would. It's not really better or worse, it's just different. But it'll seem a lot worse if you always just want it to be the way it was and always compare them to the others, rather than just enjoying interacting with whoever happens to come along.
Being part of a forum is a tricky thing, because you have to value the relationships you form and go with the flow when they end. It's tough, and it's not for everyone. I still get sad about it myself sometimes. But that's the nature of the beast.
