Pardon my posting what is merely an observation that I found amusing.
When one switches from HTML mode to AJAX mode, a splash screen, with artwork that looks exactly like Vignette Corporation's purple V's appears.
I'm sure it was completely unintentional, and I doubt Vignette would care, or even notice... but it could cause a little brand confusion to those who recognize it.
Sorry, for the fluff posting.
I hasten to clarify - not their PRIMARY logo "V", but the little decorative ones that they put in some of their product splash screens.
