I like Migg's considerations about Trepor intelligence. I think maybe the frequency of greetings could be reduced, though: are they really all that cheery? Well, maybe more than the Tlokes, sure, who greet far less often, but they do greet too much. It's like the opening scene of the Lego Movie.
Perhaps there ought be a way to filter messages by regex? I'll look into whether a UE4 add–on can be built to do so. The big difficulty would be designing it in a way that is accomodating to users who don't know regular expressions, Perl–compatible or otherwise.
