The first step to helping us out is to create an account. Using a consistant username rather than an anonymous IP address is a good thing. It allows us to recognise your contributions and it gives you some extra permissions on the site. Most importantly, it makes you seem more human and less like a machine!
Next, create your userpage. Tell us something about you. Where you're placed, your home country, what type of school you teach in, your favourite kind of sushi - as much as you're comfortable with. This helps us put a personality to the name.
Any articles around these topics will be welcome. If you are a past/present/future ALT (especially a JET) in Japan, then articles about what you are concerned about is what we want. If you think we need it, then we do!
