I have to take issue with your statement.
1. If you actually try sending a mail all you get is a returned mail.
2. I have a seen a few support tickets deleted without reply or addressing the issue.
3. Admin does not give out his skype to the general public as it is nowhere to be found on the site.
So, in short, now there is no working chat box and the above statements apply, there is no way to contact admin.
