Possible to take profile URL?


My current URL is https://www.codecademy.com/Prof_Dr_Koala
I was trying to get the username Bramvanberkel (My actual name) but it was already taken by https://www.codecademy.com/bramvanberkel (not me).
It seems that he has used the site over a year ago and is not using it anymore. I'd like to use that url for my curriculum. It looks a bit better than Prof_Dr_Koala. Also because my site is called the same.
Is it possible to send a message or mail to that user asking if he is still using the account?

Thanks in advance,
