On .org, he's got two in one thread and a third post in another thread which are truncated, including the post immediately before that one.
It looks like what I run into all the time. If you have a character which doesn't jibe well with this site, the site truncates your post from immediately preceding that letter. You have to go back and replace that letter.
A prime example is an apostrophe which is slanted, either from a quote you're trying to paste or from, I assume, a smart phone you're using to make the post. The System doesn't 'recognize' or 'accept' that apostrophe and, therefore, cuts off the post at that point.
I'm not declaring that's what it is, but seems the most likely explanation given that his last three posts have been truncated. If that is the case, however, it becomes the user's responsibility and not necessarily a 'fault' with the System. Short version: Adapt to the System because the System isn't going to adapt to you.
