I have English, German, French there. I don't want the list to get TOO long, so any suggestions here will be likely to be added. :)
Btw I don't want to support Korean, Chinese or Japanese in this particular "community edition" since there are tons of extra packages (SCIM, fonts etc) I don't want to carry. If you want a CJK version of Webconverger, I'll happily take an order to do it!
