Can you send me the cover art for the French version?  I will look to add it.

I've added that game now.

Users can gain contributor privileges on the site and add missing games themselves.  In the meantime, an email is the best way to get a few games added by admin.

The "add foreign coins" portion is a duplicate.  Please vote for that here:

I've changed the request to just be about the values for every grade instead.

This is something that users can do after using the site for a while.

They can add missing items and add missing sales data too.

Sorry for this problem.  Please let me know your user name on the site and I will fix this for you.

Please give me your user name on the site or a link to your profile page.  I will fix this for you ASAP.

You can do that now by clicking "USD" link in the upper right corner and then choosing your currency of choice.

Thank you for this suggestion.  Right now you can contact the buyer and make an offer that way.  It is slightly different than ebay process and not as streamlined (seller can't accept in one click), but it is possible right now.

I'll leave this open to see how popular a more formal process would be with users.
