This is a tricky one and I would greatly appreciate anybody's input.

In relation to the same job that my design team have been developing (a multi-national site), we have been asked to look into finding out whether there is any correct web site protocol for designing a banner ad or section when there is a global disaster or something of that magnitude.

Obviously large companies will post "deepest regret" messages on their sites after such tragedies but I wondered if there is any industry standard information/papers on this subject. It would be good to know what is good etiquette worldwide (e.g. if something like flowers is acceptable in one country but seen as offensive in another).

Another thought would be to see if there is anywhere that can view archived examples of "deepest regret" banner ads that are seen as acceptable. Is there anywhere that we could view such items?

Thanks again.
