I’d agree with that. I run a forum elsewhere for an e-zine I run and I’d say that 99% of my readers don’t e-mail or post in the forum to let you know if there’s a problem, those posting here will probably be in the very small minority. And comparatively few people know enough to be able to report a computer problem accurately to the right people and work out what’s causing it, they’ll probably just give up or think their computer’s got a virus.
