I'm going to reply to myself before anyone else gets the chance,

because I'm sure there will be some questions about what kinds of projects are good to choose, or would be "appropriate" to use the word from above. Certainly a wide, WIDE variety are possible, because life-advancement includes so very much. On the other hand, there is absolutely NO point in being able to pick just anything at all. Here are two examples of what would NOT be appropriate:
1) Something you happen to find entertaining, more than anything. That's fine, but most of the internet is devoted to cliques of people formed to entertain themselves and each other, and we here ought to do something more. Of course, you should get involved in projects you enjoy or find satisfying at some level, even if they demand hard work and are sometimes not exactly "fun."
2) Something antithetical to Prometheanism, or not harmonious with its principles and goals. Of course, it's not ever going to become a requirement for a member to agree 100% with everything in order to be involved. As Darios and I discussed at some length recently, we want to work very hard to avoid dogmatic orthodoxy in any form. That said, there's very little reason that the Promethean movement should support the other sorts of thinking and activity already amply supported elsewhere. We here should aim to do things differently, and hopefully with more advanced, innovative viewpoints and ways. And it's really part of the job of a Promethean to provide something different to you, an alternate opportunity to work for change, a different sort of working relationship with a different set of assumptions from what you get elsewhere in other, more standard ways of pursuing development or change — for example, by joining existing political action groups, or following a standard academic education, or whatever. So I think it's reasonable to ask that you pick a project that stresses something you have in common with Prometheanism, not exceptions you take to it (which of course, you're absolutely free to pursue on your own).
Let me give one social example of a project (I'm assuming Darios doesn't mind, because this was his): Darios has in the past worked with a local center/collective of a left-anarchist stripe, and some of what they do isn't 100% what he or I would normally advocate (due to the collectivism aspect in some of their thinking). However, this isn't necessarily a problem in terms of calling this a project to talk about in the movement, because the question about a project isn't whether everything involved is ideal (unlikely, if not impossible!); the question is whether the individual member might expect to get some Promethean grist for the mill out of it, so to speak. So to continue with that example, Darios expected to make some connections which might be useful, to introduce more people to Promethean ideas, and actually work on some productive steps as well (I leave it to him to describe further if he feels so inclined). So the structures you may have to make use of aren't really the issue; nor would there be a "purity test" in any sense. It's the spirit behind a specific project which is most important, and it should involve fellow-traveling of some sort, at the least. Consistency with Promethean ideas and aims is certainly desirable, but don't be put off from getting involved and proposing a project for yourself because you think it might not be "Promethean enough." The movement should always, in my judgment, remain open to working with almost anyone insofar as they share common ground, and it's just mutually beneficial to do so.
Oh, and 3) something illegal. This is likely common sense, but let me just point out that the fact that we will have a members-only section for discussing projects will not automatically make it a good idea to discuss anything illegal there, for everybody's sake. Enough said, I hope.

I hope that clarifies a bit on projects... I can imagine further questions, and I can give other kinds of examples, but I'll leave it there for now unless someone wants to hear more.
