First, I never object to anyone making an honest comment on any aspect of my writing. In fact, in a couple of stories I've made some changes due to people pointing out errors I had to fix.
2. I do not have an issue with any ISP, per se, but experience has shown (as explained in a post above) certain ISPs have a problem with my ISP and replies to those ISP usually get bounced back as not deliverable. Since the action is at the US ISP I can't do anything about it. Sorry about that.
This issue only relates to me sending the people replies, I can receive emails from them without any troubles.
Another issue I have is when the Reply to address in an email has a fault in it, the reply gets bounced. I recently had a couple where the people had the domain as .con and not .com that is an n and not an m as the last letter. So it got bounced because the address didn't exist. Another had an extra letter in their name and it got bounced.
3. My writing format is a cross between the styles for a print book, PDF, e-pub, html and SoL. I use italics and bold to help differentiate various things within the story. The use of exclamation marks and quotes is as I was taught and as my editors agree with (yes, they sometimes talk me into changing some). I'm aware the use of such punctuation does vary between some countries. I'm Australian and write using the methods taught here in Australia. One big one I have is the use of an exclamation mark for a rhetorical question, one of the US editors insists it has to be a questions mark if it sounds like a question, but use of the exclamation mark makes it clear it's a rhetorical question.
4. Now, as to the blood factors, since you've raised the issue I'll look into it. However, this story was originally written back in 2008 and that section was based on the information I had been given a couple of years earlier by a pathology nurse, and matched what I'd been told many years prior to that. In the several years this story has been available for sale on certain websites no one has said anything about the blood groups before, so I've not felt the need to look at it.
Another aspect is I was told is some situation, such as a major blood replacement situation, and exact blood group match is required. How truthful that is, I'm not sure, but I got that from different medical professionals some years ago when I started on the story.
In short, I wrote what I had been told was the true situation, now it's been challenged I'll look into. At this time I've no intention of making any further changes to the story, but that may change in the future.
Thanks for raising the issue.
