Questions about Custom Magic Weapon Creation

[HerpbertDipson]

So I've made a magic item using the editor but I don't see it appearing on any character that create. Do I need to load a file or something?

In addition to that, I'm having problems finding out how to add custom abilities. I figured out how to add the spell abilities (I think)? But the Cavalier or Samurai are giving me a harder time.

Note: They don't really have to work, I just want a check box so that I mark if I've used them or not.
