Contact Us


You may send enquiry email directly by clicking here. We are a very small team for a publication of our size. We are human and we occasionally make mistakes. We gladly welcome criticism from our readers. If there’s validity in a complaint about some content we’ve written, we will take it to heart and act upon it.

You may order our books through the order link provided in the corresponding posts. Or you may order through our distribution channels (Amazon, Lulu, …etc). They all accept credit card payments (but NOT Paypal). At present we do not offer our books in electronic format.


Defective units

If the printed book is defective or damaged on arrival, please contact the respective distributor to make an arrangement for return. We only develop and publish contents, that is why we are not able to handle shipment and return directly.
