That is clearly not true.
You went into the 1,000,000 Post Thread and made the edit there.
That is why it says "Last edited: Monday at 5:38 PM"
People can just click on that post and see for themselves. There is no point in lying about it.
That is also clearly not true.
When people make edits in The Shoutbox, they appear there immediately, while in the 1,000,000 Post Thread they appear as a whole new post.
But what you did was edit it in the Shoutbox, and you also went into the 1,000,000 Post Thread and edited it there.
Anyone can going to the 1,000,000 Post Thread and see that what I am saying is accurate.
In fact, you can look at pages and pages of that thread and you will not find the snippet "Last edited:" that the system adds in very many spots at all.
Because rarely do people go into that thread and made edits.
So why did you go back into the 1,000,000 Post Thread and make that edit?
