You may have seen a presentation in the Warpstock 2015 schedule called Unconference.
An Unconference is a loosely structured conference emphasizing the informal exchange of information and ideas between participants, rather than following a conventionally structured program of events.
The purpose of this unconference is to discuss end-user issues with continuing to use OS/2 and eComStation. Everyone in attendance is invited to present their issues, so we may make an agenda. The agenda will be created in the first Unconference session. There are subsequent sessions to be used by the items chosen from the agenda.
If the group is small enough, we will start by arranging participants in a circle, then adapt as needs present themselves. Participants should come prepared with one or more topics or issues they would like to present to the group. These can be in the form of a short presentation, or questions and topics for the group.
If issues require demonstration on a machine, attendees should consider bringing the problem system (preferably a laptop, but we could use the projector as a monitor for a desktop system) and any peripheral hardware involved.
