Tried to register

I've tried for 2 months to register my domain MadMaxStainedGlass.com only to find that I can't. Is there a department or an editor I can contact to find out what the issue is? - MAX

The only thing that you can do is suggest a site - from reading your post it appears that you've done that (possibly a few times). Once an editor decides that they want to edit in a stained glass category, your site may be reviewed. There is nothing you can do to encourage a review other than what you've already done, suggest the site one time.

There is no one to contact because there is no issue.
