The discussion was on IRC in a 1:1 conversation. The task Sahitihi wanted
to achieve was to create a soft-port capitalizing all text sent to it. I
helped her
to achieve that. I was thinking about mailing you the details, but it was
only a
few lines of code. I will also make sure to keep you in the circuit in the
future.
