(URGENT!) What other methods are there to contact users on Deviantart besides comments and notes?

Novaxis Asked: (URGENT!) What other methods are there to contact users on Deviantart besides comments and notes?

As you can see, my username here is Novaxis; a name I created 5 years ago. I worked really hard coming up with it and the meaning behind it. I use it for everything I can, and as of nearly 4 years ago, is now my home-business under the same name. My business has finally kicked off and I'm ready to start selling online, but I've run into a problem; this name that I created entirely on my own with no prior inspiration or reference has been somehow already TAKEN on several websites! My main concern right now is the one on DeviantArt; the account holder has been completely inactive since the day he started 3 years ago, and of all the places to abandon that name, DeviantArt is the worst!

I REALLY, REALLY need this name, and I've already tried sending him a note and leaving a comment on his page, but he hasn't replied – he hasn't even logged on since the day after his account creation. What do I do? Is there some way to 'expose' an email or other form of contact information I can use to contact him? This name is really important to me and I would be devastated if I couldn't pry it out of this place-holders hands… Any advice would be appreciated. Also, I've already asked the staff and they said there's nothing they can do – AT ALL.

Thanks in advance,
