Yeah worth catching up on before doing anything. When I came back after a break I also underestimated how much had changed with knife trading specifically. Made a couple of moves I wish I had not because I was working off old info from before. Here is a solid page to start with if you want to get up to speed on how it all works now. It covers which knives are worth going after and how to trade safely without getting burned. Took me maybe ten minutes to read and it cleared up a lot of things. Would have saved me some grief if I had found it earlier
