Just FYI, as of this post, every site in the flippin' WORLD says that to change your email address or password or whatever with Monster, you have to go to "your account" under "your profile". Or some dang thing like that.
However, I couldn't find it; it must have been like that before.
Anyway, currently you have to click on "preferences" which is up at the top of the page near the right when you first sign in. That's where all the good stuff is.
