EN World does have a language filter, but it is not there so you may use foul language and not have to worry about it. If we see the line of smilies, we know you've stepped over the line.
I've had to put warning in this thread about the content once before. And there's been a bunch of narrow misses since - in aggregate, they become inappropriate. If this continues, the thread will be closed, likely without further warning.
So please, as the rules say, keep it clean. Thanks, all.
