The Private Messages show who was the last poster. I don’t think it should be like this. Surely the Private Messages should show who you are having a conversation with, which they currently don’t.
Many people post a PM with the title “Hello”. So I have 5 Private Messages from different people with the title “Hello”. Now let’s say these messages were sent by P, Q, R, S and T. If I want to find the conversation with P, and P was the last poster, this is easy, as it shows who the last poster is, and I can see P as the last poster. Now if P wasn’t the last poster, then it shows me as the last poster. Let’s say Q and R weren’t the last posters either. This means I now have three conversations in my Private Messages with the title “Hello”, and with me as the last poster. I have no idea which one of these is the conversation with P, and I have to click on the messages with the title “Hello” to find it.
This is incredibly annoying. It makes sense to show last poster in posts on the forum board, but not in Private Messages. I don’t think people care who the last poster was, they care more about finding the conversation they were having with someone. If the title is unique, it is easy. If the title isn’t easy, then it can be difficult if it was you who was the last poster.
