I have to say I don't really like the idea of a tiered voting system nor a 1-BC-1-vote method; both of these types of voting give the biggest voice to those with the most money, thus an entrenching a hierarchy with power focused at the very top. I believe a system like this is unfair, and not to mention easily corruptible by those with very deep pockets (or the biggest miner!)

In my opinion a one-member-one-vote system (or one-member-n-vote) is the best way to distribute votes; this gives every member, rich or poor, equal power and an equal share in voting decisions.

We should instead give consideration to what number of votes are necessary to come to a decision on something - will decisions pass with a majority vote (50% +1member), by first-past-the-post (most votes wins), a two-thirds majority, consensus, or some other form of voting system.

Fee for entry should be symbolic(not to expensive we will find balance) because we want rise in community matter.
More members we have much stronger community will be.
And all members will have conviction that they can drive BC.

That is an excellent idea, we should focus on adoption and gaining more people who will be invested in BlackCoin as shareholders as well as investors. a non-prohibitve members fee will allow for this, hopefully more donations etc from a higher number of members will make up for any shortfall in income.
