Hi,
Next month there will be new edition of Hacker Hotel in The Netherlands. From February 10 until the 12th. I would gladly drop some stickers and cards there if someone can send them to me.
There will be around 300 people there from the Dutch hacker scene and security scene. I think it would be worthwhile to bring some attention to RIOT-OS over there.

Can somebody send me some material to distribute?
DM me for the address.
