No matter how old it is, it is still a recruitment thread for KotFE. It shows you how long they have been around and how over time they have gained a lot of members, along with their respect. KotFE isn't just a clan you join to hit ebs in. In fact, EBs weren't even around when they were formed. Joining KotFE gives you a whole other family to chat while you survive the crazy game that is kaw. These bonds are forged in more than just chit chat, but blood and iron they fight together with. People pay homage to the thread to remind themselves how far they've come.
Not all members have been playing for as long as they've been around. I myself just started KaW 8 months after its creation and even then I didn't join untila couple years ago. In the end though, it reminds you of your first days. It's more than just bumping a thread, but reliving a joyous memory.
