Michael, I looked at your Cayley Family History page, the very fist sentence reminded me of an observation I made the other day. When you do a search for any surname alone (no first name) your taken to the surname index, on the index page there is a box for say the "Bentley Project" or the "Cayley Project" which takes people to our free-space pages. I know when I go to a genealogy site, one of the first things I do is a search for Bentley. So new people could find our "projects" before they find any of the formally approved Projects.
It would be very nice, if when they click on any of last name project buttons, they got a warm welcome like someone visiting your Cayley Family History page. In many cases these free-space pages, including mine, don't "welcome" people to Wiki Tree or invite them to collaborate with us, etc. My study has more of an "academic research project" feel to it, than something that would welcome people like your family history page. So I have been considering trying to change that in the Bentley Study.
I wonder if others have thoughts about the role the ONS free-space pages play in acting as "ambassadors" to our surnames, whether we intended that or not. I might make this a new question, but maybe others will see it here and share thoughts. If others have good examples of welcoming people, I'd like to see ideas.
