Can't find my old posts

[Nathan Nakaguchi 1G]

After I've commented (or I look at one of my comments) when I click on the box on the right with my name I see that it says I have posted 10 times, I click on it and it shows me my posts, but I can only find 9 of the 10. I remember commenting on a photoelectric effect post this week but I can't find it again, do I have to make another post to meet the 5 a week requirement?

If you go up to quick links in the top left corner of the page, there should be a section called "your posts" and that will show you all of the posts you've made. If your tenth post doesn't show up, I would make another post just in case.
