My two cents comments:
And is anyone else interested in this too? I would love to know, as networking could be the key to creating this.
Networking is what we are all about so start a thread somewhere as you please: Perhaps here: Daily Life As An Epicurean We could expand into a separate section later.
Can we agree on a set of Epicurean postulates?
That is always hard and I wouldn't recommend you start with a full set or you'll never get started. It was very difficult to come up with the "Not-NeoEpicurean" list, even though such a list is needed for an elaborate project (like this forum). As an even more basic "litmus test" the set of four premises in the gold box is what I currently recommend as a distinguishing starting point for consensus in any level of complexity of project. Even there, while the first two are clear enough, the "all good and evil" quote is what I suggest to focus on the "negative" assertion that there is no absolute virtue, and the "pleasure is the beginning" is the focus on the positive assertion that feeling is the guide. If people can't agree that Epicurus was at least firm on those basics, my personal view is that they really aren't Epicurean at all.
