Derick Rethans has posted the official announcement for this year's PHP Vikinger event held each year in Norway:
The PHP Vikinger is a community-driven PHP event that will be held in Skien, Norway on June 9th. Like the famous Foo Camp and Bar Camp, PHP Vikinger is driven by its attendees. The people who come choose and present the sessions at the event.
The attendance is a mix of invitation and registration with invitations sent to members of the community and previous attendees (with spots open for those that register too). In all, there's around 100 spots open for all. Registration is free and a lunch will be provided. To get complete information on the event or to submit your information for registration, head over to phpvikinger.org.
