I should NOT have to tell that lvl9 iczer that he gets a Starter Switcher, and can exchange it for ALL 4 starterfiles. It should be in the welcoming message to new iczers. The guy was shocked to hear. He also had no idea where he could exchange it and that it was for all 4. (and i've heard this before from other low lvls)
Go edit it in the email. Go put it up as advertising somewhere. Mention increased exp upon beating higher leveled iczers aswell somewhere. It's these little things that take a minute, but can mean alot. Go sell your product.
