Use the Forums, Luke!
If you have a query, please check the Frequently Asked Questions first. If they don't help you, or you have a suggestion for a new feature, please head over to the Dejal Forums and post your feedback there. That will allow others to comment (more support for a suggestion means a quicker turnaround to implementation!). The developer will reply promptly.
Please do consider using the Dejal Forums. But if you prefer to keep your query private, you can send an e-mail. We (meaning David, the developer, or his lovely wife Jennifer, who also helps out with support) will endeavor to get back to you as quickly as possible.
Again, please do consider using the Dejal Forums. Otherwise, you are welcome to use this form to send feedback. We read all feedback carefully, and if you provide an e-mail address and we have any questions or comments, we'll be in touch. If you do want a reply, please ensure your e-mail address is entered correctly, and your e-mail client will accept mail from dejal.com. All fields are optional, but more information is more helpful:
