I think it'd be nice to have a 'view your post' option, where you can view your entire post history - it's how I keep track of threads I've posted in, to be honest. It's kind of a pain to keep on having to visit my profile to view my post history.

Any plans for that to be added in soon?

Well you can use the subscription feature. :3

As Razor said there is a subscription ability to subscribe to threads you want to keep track of. But now there is the ability under your own post to search your posts. Currently the buttons are switched around though so it should appear as buddy at this moment. But it will lead you to your own posts.

Just click on your underlined name in the top right corner of the screen. That'll take you to your profile. Then click on the "Statistics" tab. Then click on "Find all posts by ___."

That's how you find all your posts. :D

OR, you can click the Profile button under your post and that'll take you there instead of clicking on the right top corner link.
