Ask questions, report problems and bugs, and chat with the FlatPress developers and community on the Support Forum.
Before you ask your question, make sure you checked if the FlatPress Wiki already has the information you need.
The FlatPress team can also be contacted directly by email. (If you have support questions, bug reports, feature requests et cetera, please use one of the other mentioned ways instead.)
FlatPress is an international project, so our preferred language is English. You might find fellow FlatPress users speaking your language on the forum, though :)
