The web-forum for the project "Historical Worlds" at the Museum of National Antiquities in Stockholm has opened a forum in English. You are all welcome to post if you want to reach large parts of the living history experts and enthusiasts in the Nordic countries. The site has a really active forum about living history, where members from all Scandinavian countries post (by now about 750 members and 12 000 posts). I often receive questions in English and therefore I have started an English forum for questions from abroad. Lots of members are museum employees and have a large knowledge on (in particular) Nordic history and archaeology.
Only one of the forums is in English. All other forums are in Scandinavian languages. The English forum, I believe, will be read by most of our members.
The forum: http://www.historiska.se/histvarld/forum/
We also have an English version (work in progress) for the costumes part of Historical worlds: http://www.historiska.se/histvarld/eng/drakt.htm
