[rab] Ah, but are you in the same situation as Nottingham where it's compulsory to use the corporate identity (and to make sure you're using the latest up-to-date one -- we recently had a wavy line representing the Trent River removed) on any materials designed for outside consumption (eg talk slides)?
I presume people read about East Midlands airport which wanted to get a new name everyone could identify. It's now called Nottingham East Midlands, despite the fact it's not in Nottinghamshire and the nearest places are Derby, Loughborough and Leicester.
[rab] No IE (on Windows, anyway. Dunno if IE5/Mac works) supports transparent PNGs. [Dujon] There's something wrong with your Firebird if it doesn't support transparent PNGs - Firefox is the way forward, of course. There are actual usability and performance improvements post-0.8.
