[sudo-discuss] don't put my email address on the omni calendar

I don't know who posted this, but I am happy about everything except the fact that my email address is presented (in text with the @ symbol and all) without my permission, on the open web: https://omnicommons.org/calendar/events/hardware-hack-night-2015-11-03/ I don't know how to edit this calendar entry and remove or edit my email address. Can someone remind me how to do it, or do it for me? Also I would like to know who posted this so i can make sure they understand that they should get my permission before posting my email address anywhere. thank you! -jake
