Yeah, that was my concern when I initially dealt with it via filters. My other concern was that filters are checked quite early on in CF_MEH and the message could potentially (albeit a slim chance) get filtered out later on during the function.
Thanks for that example code and for the advice Phanx. I'll get stuck into it now.
