Hi,
over the last years some of the RIOT maintainers presented RIOT at Embedded World. This was always supported by companies or other organizations, such that RIOTers did not need to pay for the booths. Unfortunately, this option is not available this year, so far.
If you attend Embedded World and show RIOT, or if you can spare some space at your booth where RIOT developers can show some RIOT applications, please reply, either on- or offlist.
Thanks matthias
