Unfortauntely Silverpaw is a name I didn't have the fortune of encountering on the forums, but I recall reading Zoltan's posts a lot when he was still with us. A very brave chap that really brought out the community spirit here.
I'm sure there are others I don't know about, maybe who stopped posting here before they passed on, but I'm sure they all leave their mark through friendships with other members.
This place really is more than the sum of it's current parts - it also encompasses former members by their association with the present.
