Are you in contact with the Pirate parties of different countries? Your party sounds like it uses the idea of "liquid democracy" which is discussed quite a bit by the Pirate parties if memory serves right. I think the German one at least discussed some tools to use/build for the entire vote/poll mechanism which I assume is built into your collaboration product.

You'll probably end up in some upcoming startup books as an unusual MVP (is it M?). "Found a political party".

Good luck, political change is really hard and I do like the concept of more direct wisdom of the crowd like politics. I'm not sure about your product but access to governments and understanding how they work is pretty valuable. Government tools tend to be internally-viral (one community usues it, it spreads). I'm curious if the fact that you are also a party might be dangerous for the product though. Pretty often useful stuff is blocked on principle so for example if your party seems "left", conservative city councils might not use your tool due to that (likewise the other way around). Pretty interesting problem to have.
