Regional Symposia
Symposia are smaller conference-like events that are arranged outside the Plone Foundation's guidance and endorsement. The Plone Foundation is urging smaller conferences to occur in regional areas, and you don't need approval from the Foundation to arrange one of these - although they should at least have a bare minimum of professionalism - proper program, reasonable attendance fees, etc.
