Users cannot submit "proper" reviews directly, right. Just because this ability reserved for the staff.
But you can:
1. Found the "safe" game (get it from "safe" list on site, or ask about your one).
2. Write the review about it and make several screenshots.
3. Contact Japo and request ftp access. And upload all above. Maybe with game, but not always (FTP have it's limits, so most CD-version will need to be hosted somewhere else).
4. Give sign that you did all of that somewhere in the forum.
After that someone will put this review on site. I can, for example.
