Just now I've been experiencing a problem with a lot my post edits - I edit and save the post, but none of the new material shows up. I click the edit button again; the information is still there. Yet whenever I click "save", it refuses to show. Don't know if this is just for me or for all users.
You don't realize how bad it actually is! I survive off post edits. My tendancy is to write first, and think later. So I kinda depend on that edit button before the 30-minute timeout...
Another thing I've noticed lately is that my posts no longer have the "last edited by..." thing stuck to the bottom of them after I've edited them.
