[arch-events] FrOSCon and visa

The German consulate wants to receive some kind of invitation from FrOSCon organizers to give me a visa. The girl from Business Support Team who is in charge of the visa receiving process sent an email to FrOSCon team last week, but still no reply. Does anyone know other ways to contact them (phone, mailing list, personal contact)? -- Roman Kyrylych (Роман Кирилич)
