In 2008 Marc Dechèvre discovers Joomla, its strengths... and the power of its Community.
That Community gave him a lot... so in return he is very pleased to try to give back.

That is why he's happy to be a regular speaker (in French / English / Dutch) at international conferences (JoomlaDay FR, JoomlaDay NL, Joomla World Conference, J&Beyond, CMS Africa Summit) and at different Joomla User Groups : JUG Wallonie, JUG Vlaanderen, JUG Maastricht, JUG Ouagadougou, ...

He regularly publishes articles about Joomla in general and about Custom Fields in particular:
