Please stop using HTML for your emails. Heck, use a better email package
(your emails have looked wonky for a long time).

See below for the problem with using HTML. There is *NO* separator between
your message and the message you quoted. There isn't anything that says the
quoted email was from Geoff. Quite impossible to read/parse/whatever.

I believe netiquette generally says to use plain text for mailing lists. Not
everybody out there has HTML-capable readers.
