I started by trying to find some old posts of mine from 2012 so I could verify when my peachicks were born, but the "all posts" link in my profile will only let me look at the last 1000 posts, which were all made in the last 30 days. I asked over in the feedback forum and was told it was probably a limit, which makes no sense t me, so I found a way around it, though seems like some people are missing posts. Some are missing a few, but others are missing several hundred.
Anyway, I was able to find my first post, as well as first post from a bunch of different people and it was interesting to go back in time and read them, that's all, nothing worth gossiping about.
This link does not show all posts, it shows 100 pages with ten posts on each page.
