I can only see it if they have an alias and I suspect others may be mistaken.
When I click on the number of aliases next to their name, I get this page.

I've got no idea how many logins, emails or bookings I've racked up under my profile. I'm kind of interested to see how the ratios would compare.
Looking through the info visible on my profile there is a Login history page, but it only displays the last 100 hundred logins info about date, time, IP and ISP info, plus the browser used (could be some pretty revealing info in the wrong hands). Nothing to indicate a grand total of logins.
To find out how many emails or bookings I've made it looks like the only option available to me is to count through and total them up.
I wonder if the "bookings made" figure that is visible to SP's differentiates between confirmed bookings and unconfirmed requests? I have at least a couple where the WG didn't confirm before or after we met. Most notably when it was a disappointing visit.
