I've looked all over the place and I can't find where to put my registration code in game. I was happy I found it in my e-mail, however the directions given in it don't apply anymore I guess. Help please.

Go to User CP > Edit Profile > Toribash Registration Key and put it there.

Thanks, it's already there I guess. What does the old-schooler thingy do? Any bonuses with the Torishop?

You shall get a free Head Texture and, possibly, in the future, an exclusive joint/set [all the old-schoolers are waiting for it].
