Yes, please migrate the content from the old OS2 World. The content is valuable to people like me who plan to remain with the platform for a long time to come.
All old articles will be migrated so no worry and the old forum will be moved as well; we talked about migrating the old forum post into this new forum, but problem is that there is just too many user accounts not in use. So I think that it might be better to move the old and make ref points to old posts or ref points from old threads to new threads here in this forum.
