Sorry for delayed response.
You should be able to send a message to Mike using the ‘Website User Lists’ link in the list of links on the right hand side of the page.
This lists all users under ‘Members’ or ‘Non Members’. Clicking on the name of the person brings up their profile and their email address.
Your comment has reinforced a view that the home page is getting a bit full / difficult to follow. I would welcome ideas and suggestions to improve the website for users.
Let me know if this doesn’t work.
