It sounds cool, and you have my addy. I would prefer to use my sign-in name since it's from the FOS. Also for security reasons. I'm not comfortable having my signature traveling the world. No offense to the "family". I have questions, too.
Where does one get these huge envelopes? Will everyone have access to them?
Is it one big card or many cards? Because shipping many cards could get very heavy=expensive for the last remaining signers.
Would it be easier to have a big poster size paper that could be rolled up and sent in one of those poster shipping containers? Or is a poster too fragile?
And last, how would it get to the band?
I'm not trying to be a killjoy, I just like to be aware of any problems that could arise before hand, so the trouble-shooting can begin to ensure the success of the project. Whatever you decide, count me in.
