Four mailing lists are available to help facilitate discussion among developers in the Joomla! community.
End users are encouraged to use
Please understand that these mailing lists are strictly reserved for developers who create Joomla! extensions and write core code. In advance, thanks for respecting the guidelines.
Joomla General Development is a list for developers in the community to interact with one another, to ask and answer questions, find collaborators on project ideas, and consider how changes in coming versions might impact extensions.
This list relates to general topics about Joomla development, including development of third-party extensions. The types of discussions one might find here could include issues related to creating a router for a new component, or how to use the JForms API introduced in 1.6, or problems migrating a 1.5.x extension to Joomla! 2.5 or 3.x.
From these discussions, it is hoped that developers might summarize important topics and learning material and share that information with other developers on the Wiki.
If you are a Joomla! developer who creates third party extensions or participates in Joomla! core development, you are welcome to sign up for this email list at Joomla General Development list.
This list is for discussions around building the Joomla! CMS. If you are a Joomla! developer who contributes core CMS code, including new features, you should subscribe to this list.
Questions about impact on extensions should be asked in Joomla General Development list not this list. End user questions on how to use the CMS or share ideas on improvements should be posted on the Joomla! forums.
Following the January 2009 Joomla! Developer Coordinator Summit, a list of "strongly desired" items for 1.6 was shared, along with an invitation to third party developers to take an item and contribute the feature to the core CMS. Discussions related to the development of those items are good examples of the type of discussion one might find in this list.
This list is open to those who contribute code for the Joomla! core Framework. End user and extension development questions should not be asked on this list.
The mailing list is set up for Q&A format to please ask any questions you have about using the Joomla Framework, improving it, fixing it or even future directions.
The Joomla Framework code can be found at:
The Joomla Framework is installed with an application called Composer and you can get it from http://getcomposer.org - if you are having any problems getting Composer working, please use their mailing list at https://groups.google.com/d/forum/composer-dev for support.
The following lists are deprecated. They are included on this page for completeness, and because you may still find answers to your questions in the archives.
This list is open to those who contribute code for the Joomla Platform. End user, extension and CMS development questions should not be asked on this list. Discussions in this list will focus on platform development. Joomla Platform Development
It is not anticipated that a strict set of rules will be needed for the developer lists. Participants are expected to comply with the Joomla Code of Conduct.
Time is a precious commodity for everyone. It is appreciated when questions are researched properly, prior to asking questions, and if community members help one another. It is especially appreciated when people take a bit of time to document a solution and share that with others on the Wiki.
