I know this has been discussed but i have a simple suggestion that would make everyone's life a lot easier.
When you click on inbox and then message history, you are taken to a page that shows links to all of your conversations with people in the last however many days. When you click on the conversation, it takes you to your message exchange with that person.
For example. I click inbox, and I see:
Gator. and mrstskier
Gator. and some guy you offered to buy something from but forgot his name"
There needs to be a better way to organize this, it's too hard to find specific messages and keep up with conversations. I PM a lot and I often have 2000 messages from mrstskier saying useless things with one message in there from a random dude saying something about a transaction. I don't want to have to sift through 30 pages of messages or try to remember this dude's name.
I know I'm not alone, maybe this is in the works, but it'd be a very worthwhile change
