As promised a long, long time ago, I'm practically finished with the on-site messaging system. It will replace all the current facilities that readers can use to send messages to authors and will allow authors to reply to readers on the site.
1 - This will help avoid using emails for feedback with whatever drawbacks email has (messages lost to spam filters etc...).
2 - It would allow authors to report abusive messages.
3 - It allows authors and readers to stay private while facilitating communications.
1 - Due to the volume of messages flowing from the site currently, messages will have a short lifespan. Messages will be deleted from inboxes after one year.
2 - There will be bugs that will need squashing, so growing pains at the start.
So, don't be surprised when as of Saturday June 3rd, 2017 feedback by email dries up. The messages will be accessible on the site.
I would need everybody to report whatever bugs they encounter so that I can address them.
