Hi, I volunteer to help with the Wikimania 2018: to promote the call, to recruit speakers, to review submissions etc. I am a long time “wikipedian”, with first time editing already the very first year of the project. I have also worked in many conference program committees of various kind of international research conferences. More information about me is available in here: https://teemuleinonen.fi/about-teemu-leinonen/ - Teemu
