Ah, how I love a barely veiled call out.

First, you seem to have misquoted something there: (The proper quote, taken from my outbox. At least keep things in context, if you're going to do this.)
The attempt was to encourage a discussion in open channel, rather than expecting a personalized explanation in private. The entire point of a forum is open discussion and archive information. Effectively a forum is a knowledge base. When you request clarification that would lead to normal conversation, it is not only polite, but very prudent to do it in open channel. After all, private messages are for private issues.

Now, since most of CD already thinks I'm an $@#$@#$@# (And I don't blame them, as it is quite hard to carry tonal inflection across the intertubes), I may as well move on to the issue of proper communication: In my field of work as well as the majority of the professional sector, it is impossible to carry out business without impeccable communication. A single misspelling reveals a lack of focus on detail, something that employer do not look favorably upon. My terse tone was a failed attempt at conveying this lesson (and an important one indeed, as it lost me a fairly decent contract due to a single spelling error...), apparently. I have always been raised on tough teaching, and I suppose it's a weakness of mine that I emulate that myself.

On to the claimed "refusal to reply." Keeping up on seventeen forums, six email accounts, and three IM accounts is a bit of an overload. Apologies for missing one post (I see now that you posted your question back in the forum, I'll head over there to answer it next), but there has simply been too much to keep up on.
