How to find a User

I have just signed up to OSM, and to the Community. When I signed up to OSM I put in my full name as “Tony Maynard-Smith” but was told this was already taken. I have not encountered this problem before, so would like to find this user to see if it is actually another person, or whether I already signed up some time ago and have forgotten about it.

The URL is
Like this
Which is indeed taken.

If you recognize the blue area on the map of this user stats page, it’s you.
