Where I used to work, I was considered something of an Excel expert. But for the most part I've long ago given up tackling Excel-specific questions in the forums - simply because there are so many people around who can do so at least as well (and often far better) than I can. Instead, I concentrate on MS Word (especially in the field-coding arena) and its interactions with other Office products (mostly Excel). Which, I suppose, is why MS gave me Word MVP status.
