I'm sorry to OT here.

I've received a pm (private message) from you but cannot reply through pm.

Error message says "bpmphoto has chosen not to receive private messages or may not be allowed to receive private messages. Therefore you may not send your message to him/her."

The answer to your question is ....
Yes, I am the writer. If there is anything that is sourced from other places, I will acknowledge accordingly.

Please email me instead at zoossh@starhub.net.sg if there is anything else to enquire.
