@BasilHugh,
I am relatively new here as well.
In the upper right corner of the page, you will see [Inbox] to the right of "BasilHugh". That is where private messages will appear.
If you click on my name you will go to a profile page.
On the right of this you will see the profile picture, beneath which are several options including [message user].
I will send you a message you can look for it in the [inbox]
---------------------------
Actually I did attempt that, but you are registered only under [
Groups] it appears. There is a separate tab (near top) for [
Forums]. If you register there as well, then I believe you will have messaging capabilities.

The link to your paper was removed because, academic and/or financial self-promotion is just about the only rule on A2K.
I am not an administrator of the site, you might try posting it as a comment now, rather than as your opening remark in a discussion.
I am not exactly sure how the rules are determined.
I think that my expressing interest might be enough for it to not appear self-promotional.
