Chat

Hi! I have some problems understanding how the site is set up regarding trading. This happened:

1. I got a trade offer
2. I note that some of the cards he wants is in the wrong condition, so I used the mail function and mailed him to say this.
3. I got the same trade offer again. This time I saw it in the mail, and it says "During the last day you have received some new chat messages on deckbox! Check out the following links for details: URL"
4. I click the link, but comes only to the trade offer, not to a message from the trader.

Q: Am I missing some "chat message" view on the site?

Thanks for any answer.
