Such a notification can be sent, but only if someone posts the Wonderful WikiTreer template ( {{Wonderful WikiTreer|g2g=xxxxxx}} ) to the person's profile.
The person posting it needs to include the actual g2g thread ID# where I have the =xxxxxx so for this to have notified you, it would need to include g2g=1362159 in the template when posted to your profile as a comment.
(I did this for a while for some folk, but after being rudely attacked for whatever the reason was (I forget now), I mostly stopped doing it except for folk with whom I have had very positive interactions, making it clear I am only the "messenger", not the one making the g2g post.)
Sometimes it seems to work well, including the image, other times for whatever reason the image doesn't show.
