NANOfutures is organised in working groups. You can see the list of working groups under 'Community' in the Member Area.
If you would like to participate in a working group, click the 'Join' link right to the group. You can join more than one group if you like.
Every working group has discussion forums and potentially polls, created by it's members.
Beside the working groups there are pools for documents, interesting links and related events to share with the community. Don't hesitate to extend these lists by uploading own documents, adding links or posting an event if you know about one.
