Talk:Invisible ink

No, invisible ink pens do tend to have two tips, one for encoding and one for decoding. I think the cover message is typically done with another pen. --Daniel C. Boyer 16:38 22 Jul 2003 (UTC)

IUPAC spelling

Multiple changes of sulphate to sulfate are a BE to AE conversion, which WP discourages. WP policy is to let BE and AE flourish. Probably should be reverted. ww 15:57, 19 Jul 2004 (UTC)

No, it's a conversion from the old, archaic spelling, to the spelling recommended by the IUPAC.

And colour -> color? Never mind ;-) — Matt 00:32, 20 Jul 2004 (UTC)
Considering colour redirects to color and the MoS says: "Each article should have uniform spelling and not a haphazard mix of different spellings (it can be jarring to the reader). In particular, for individual words and word-endings. For example, don't use center (American) in one place and fibre (British) in another".
If it makes you feel better, the IUPAC recommends Aluminium and Caesium, so you Brits have two out of three. Humor also redirects to humour.

Oops, I was just joking about "colour" -> "color"; sorry to have put you to the effort of digging out the Manual of Style ;-) I'm curious; is using IUPAC names now official policy on WP? — Matt 02:07, 20 Jul 2004 (UTC)
It's not an "official" policy, yet. It's more of an unwritten rule that anyone who contributes to chemistry related articles uses the IUPAC spelling. We've never had a problem with it yet, though I'm going to suggest it become an official policy to avoid disputes.
