I just noticed a new Finnish Flash Community site:
To be honest, I can’t read most of the content on there, but there is a lot, and it appears to be updated often.
Btw, if you know of any other useful Flash Community sites not in English, then post them in comments section.
Btw2, we have a lot of localized content on the Designer and Developer Center. Just choose your languages at the top of the page, under the menu.
