Ha! I had to re-read that post, it made me chuckle.
There was an idea floating around of custom language filter entries; I'd totally like to take that up a notch and have SE allow us a completely separate chat filter to their built in one; that way we can add our own entries into it and leave the rest of the chat log (And Cal's serenading) untouched~
I don't use the ingame chat filter just because it is so awful, but I'd totally love a customizable one :3
