Yes, that's very sad, indeed. Especially when viewing the fact that
there are web sites that can help you "digitally sign" documents by
pasting either a scanned signature or "Your Name" in a chosen font under
the document. And these are deemed to be legally valid ...
Anyway, forgot one of the arguments in my original post. Even if it
might be difficult to get this kind of line of argument across in court,
the availability of such a tool may also make it viable for "the
accused" to present a differing chat transcript with alternate content.
I'm not a lawyer at all (just a geek), but I think the presence of a
consistent transcript with different content may make the opposite
side's case weaker. So it might be valid to provide such tools to enable
How much impact it will have is then a completely different aspect.

Thanks for that link. It's an interesting summary of the legal
situation. I guess it's somewhat US-biased, but then most (more or less)
sane legislations will have a similar position on it.

Well, you can never trust your common sense to be upheld in the presence
of over-paid, legal spin doctors ... :-/
