In reply to DaveHK:
No criticism, but there's some subtle semantics going on here that interest me; it's a classic example of how easy it is to be misunderstood in text rather than speech
I think because you wrote 'usual channels' your message contained (to many people anyway) an implied message that this channel is unusual, and hence a criticism - why not use the 'usual channels'... If you'd written 'other usual channels' the potential to see criticism would've been much reduced. If you were speaking, your tone would allow you to steer clear of the implied criticism.
