As explained here, JAGA is currently not actively maintained. Nevertheless, as far as time permits we are happy to provide any support we can.
The preferred way to contact JAGA developers is via the forum.
This has several advantages:
- If someone has a similar issue as you, it will be easier for them to find the answer if it is already on the forum.
- If you post your questions to the forum, there is a chance that some other user may be able to help you. As a result you may be able to obtain assistance quicker than from the JAGA developers directly.
