Ah yeah I read about Eleusis some, was before my time but he is famous and should certainly be included in the history of the scene as well. JFL, was that the poisonous non-consumables site? That was also before my time, they were one of the first internet vendors though. Astor it will look a lot like a forum. Imagine that there is a Bitcoin icon under Avatars on the forum, like the send a PM button. When you click on it, you can select a number of Bitcoins and hit send, and then Bitcoins are sent from your wallet to the person. You could have product listings by creating a blog, which would essentially be a thread that you can send posts to but others cannot reply to. So you could make all of your product listings and have them posted and be able to update them, people who know about you can download this page without anyone being able to tell they did, then they could use the same system to send you a private message saying they are placing an order and the details of it, click a Bitcoin button and have coins sent to you for the order. And people who are networked together could use the same system to have a thread that anybody can post to and that is related to your services, so they can share reviews with each other. So Blog: A dynamic message referenced by a long term public identifier string, only you can modify the message and anyone with its identifier string can download it, this would be a spot where people could list products if they wanted to PM: A fixed message referenced by an ephemeral shared secret identifier string, Alice tags a message for Bob with a secret one time use identifier shared between Alice and Bob, and this allows Bob's client to obtain the message after it arrives at a PKS. Group PM: The same as regular PM, but instead of tagging a message with an identifier for Bob, Alice tags it with identifiers for Bob and Carol, and encrypts it so both of them can decrypt it. Forum: The organization of group PM's into a forum like visual structure, which takes place client side, with each user being the admin of their own perspective of a forum, which itself is crafted using the collection of group PM's as its' threads. So when you gain access to a group PM discussing Astor's blog, you can move it to the subforum vendor reviews, which exists entirely client side on your own system, and when you gain access to another group PM discussing the same thing you can merge it into the original group PM, and replies are compartmentalized such that if you respond to a post from the original group PM it only goes to people in the original group PM, and the same for the secondary group PM, but it gives you the impression of a single thread of messages and of participating on a regular forum on which you are the only admin.
