Do not write to the dev list if you have a question about Drools: use the user mailing list or the user forum instead.
Only write to the dev list if you're working on the Drools source code itself and want to discuss source code changes and design:

• Subscribe to the dev mailing list
• Look through the archives on gmane or mailman.

Note: The audience on the developer list is much smaller than the user mailing list. All Drools developers also watch the user mailing list.

For research paper related discussions (excluding anything that belongs in the user mailing list), use this mailing list.

• Subscribe to the research mailing list
• Look through the archives on mailman

Note: The audience on the research list is much smaller and more specific than the user list.

In general, the Drools core developers will only support the latest release in the free mailing lists.

The user mailing list is for general user querries about drools and how to use and it problems with using it. The dev mailing list is for more hard core discussions about about developing drools itself and general rules/ai theory that might apply to future drools features.

When asking questions, especially about bugs, you should always state which version of Drools you are using.
