It's a pity they waste such a historic site with sub-par support.
There's really not much missing.

Major issues and wish list:

• Refill the hot wallet more frequently
• 2-factor authentication. I suggest RFC 6238 one-time passwords. That will work with many different authenticator apps.
• Fix the leader board prizes

Minor wishes:

• Rewrite the Flash-based slot game in JavaScript. Less and less users have Flash installed.
• Optimize images to save bandwidth. The PNG images on the front page are 215978 bytes. They can be optimized losslessly to 85095 bytes.

... and the site would be almost perfect, in my opinion.
