I'd like to see this too, a personal posts archive thingy, just like any other generic forum has.

Now there's only a button to favorite topics, so you can keep track of the topics; but can't keep track of the inside posts you did, be it a week ago or a year ago.

Or... you know, if and when GOG will implement profile pages with a PM system, they can easily add a page of all your past posts there too.
