In about 10 days, we’ll be switching to a new and super cool profile system. Part of the changes will include a new and easier to use design for private messages. Unfortunately the new private message system and the old one are not compatible and after discussing it internally, we decided to go ahead with the improvements at the cost of losing all messages stored in our old system. The takeaway here is that in about 10 days, you will not have access to your old private messages anymore. Any messages sent between now and the upgrade will also not be saved. If you have something important in your private messages, you should copy them somewhere else.
