It might in fact be a dumb move to sign messages to the cypherpunks list -- proving that you wrote whatever, when for example the USG adds cypherpunks to it's growing list of terrorist organisations.
We're an 'organization'? Where is my monthly newsletter?....;) We should also pick our treasurer with some care. It is the prime target for law enforcement since it provides them access to the money records. In general I have to agree with Adam though, in the real world with ubiquitous and surreptitious monitoring signing documents is actualy a liability in many if not most cases. About the only exception is dealing with a contractual relationship. ____________________________________________________________________ | | | The most powerful passion in life is not love or hate, | | but the desire to edit somebody elses words. | | | | Sign in Ed Barsis' office | | | | _____ The Armadillo Group | | ,::////;::-.

There are a bunch of people subscribed to a mailing list called cypherpunks. There is no organisation, this is an anarchy, as can be readily observed :-) I only used `list of terrorist organisations' because I think that is the US government term for their little black list.

Even for contracts I think you would be better off not connecting to your meat space persona if you could help it. eg. Use a nym, post a bond with a high reputation cyberspacial arbitration service, use designated verifier non transferable signatures to allow the arbitration service and other party to the transaction to verify your signature, but to make the signature non-transferable to other parties.
