It does seem kinda cool actually. but yeah, of course you could always throw it in your sig.
hmm. maybe... but somehow i think it would look out of place over on the left there. your SIGNATURE area was originally intended to yield your name correct?
i just wish more people would do that, its much easier to refer to people and coverse with them when you can refer to them by name. we could all be...on a ...first name basis.
maybe a spinoff of this suggestion...maybe on the profile update page, there could be a small paragraph giving ideas on what sort of format the signature box should be in. explaining about the 600x150 sig size, suggesting you provide your name etc. I see it to be that there wouldn't be as many sig violations that way, and names would be abundant, and we would discover there are even MORE Johns around
