Sander Potjer Joomla! Expert

My passion for Joomla began in 2005 when building a site for my rowing team. I was immediately impressed with Joomla and the community surrounding it. Soon I became personally involved and co-founded JoomlaCommunity.eu and started the Dutch Joomla User Groups together with others.

From this community the Dutch foundation "Stichting Sympathy" emerged, to promote and support Joomla in the Netherlands, which I chair. This foundation also organizes the annual Dutch JoomlaDays. Internationally I volunteer to Joomla as team leader of the Joomla Volunteers Portal team.

I am co-owner of Perfect Web Team where we develop, maintain and support web solutions for complex situations based on Joomla. I am also the creator and developer of ACL Manager, a popular Joomla extension that simplifies the management of access permissions.

Joomlers on the New Joomla! Volunteers Portal

Joomla is a very unique Open Source project. Joomla never had a benevolent dictator or a corporate backer. There is no office building and Joomla has no paid staff. Still, Joomla has grown to be one of the most popular CMSs in the world, thanks to volunteers!

Creating an Article in Joomla! Has Never Been This Easy!

Joomla is very flexible and has many possibilities. A disadvantage is that working with Joomla can seem complex because of all of the setting and navigation choices. For a Joomla specialist this is usually not an issue, but for many end users it can be a stumbling block. Adding new articles via the Joomla frontend is often one of the first things end users face. This should be a simple operation, but many experience this as very complex.

Complex Joomla! 1.5 Migration With Minimal Downtime

Joomla 1.5 is not supported by the Joomla project for quite some time now. You still can continue to use Joomla 1.5, but (security) updates will no longer be released. Furthermore, both Joomla 2 and Joomla 3 have many new features and improvements. Perhaps you recognize it: once you use Joomla 2 or Joomla 3, managing a Joomla 1.5 website really feels old-fashioned and you notice how greatly Joomla actually improved.
