What is a JoomlaDay™?
A JoomlaDay™ is an event about the CMS Joomla! During one or several days, the Joomla! community in the area will have the opportunity to gather to learn, teach and, ultimately, to share experiences about this content management system.
Are these events commercial?
No. A JoomlaDay™ is a non-profit community event, and neither the organizers nor the speakers can receive any financial compensation for their work at the event.
If that's the case, why are there sponsors?
One thing is that the speakers and organizers do not make money with the event, and another that they have to bear all the costs involved in organizing it. Events can, and in fact the Joomla Project encourages them to do so, be open to sponsors, who in exchange for reasonable publicity during the event (also before or after in the various media in which the event is supported), will offer an economic compensation to cover all the expenses of the event: renting a venue, catering for the breaks, professional recording of the talks, travel and accommodation of the speakers.
