Guests and others--

Regarding GUEST X is fine, as long is it's unique to you ...

I've noticed that when some folks read this sort of sentence (a lot of the Brits in particular), they tend to hear that a rule has been laid out to them, and when other folks read this sort of sentence (especially USers), they hear an encouragement, an exhortation, perhaps a practical reality. It's a difference in cultural expression, of the sort members have freely discussed here for years.

So I don't think Dick means to make a requirement. It's just a distillation of the friendly advice many, many Catters have offered. It's purely practical-- rather than quoting long passages from someone else's post, as many message boards do automatically these days-- we prefer to just address the person whose post we're responding to, around here, and maybe italicize a brief passage that sparked our response, because that's how the forum's technical design works.
