I posted a message here.
Then I thought I should rewrite the entire message, but after typing a couple of words, decided the original message would be fine, so cancelled the edit.
However, when I went to edit the message again, the only option was the edit the couple of words from my cancelled edit.
To edit my posted message, I would have to copy/quote it into the message box.
Just FYI, in case this is something you'd want to look at.
