Re: ORLY?
Previously it might be an option to print it to an image or use a screen shot, then edit that in something like GIMP
Its a shame its not an option to give up the silly charade, like AC said.

some kind of digital cert / encryption is whats needed , and probably used in other things like software signing.
Whereas in office paperwork etc , we are still stuck with "Make yer mark here pilgrim, if you aint a writer jus do an big ol X"
