The Wougnet Mailinglists where hosted by Kabissa. In May 2009 they switched off their hosting services and moved into new ventures.
Wougnet decided to move their mailinglists to Pamoya. Pamoya could give them new Web 2.0 functionality, like user profiles, full text search, social networking and much more. Wougnet could not have build this only for themselves, so they decided to team up with Pamoya.
All the mailinglists archives are transferred to Pamoya, as well as all users and memberships.
