No, an ActoShare is not the same as a dollar. It works like this:

(Your ActoShares / Total Number of ActoShares) * Community Fund Value = Your Earnings.

You can view the total number of ActoShares on this page.

At this point, you can only trade your ActoShares for a cash payment via Paypal -- you can't go shopping with them just yet. (We're still working on that part). But you can earn shares and cash them out and use that money to shop for products listed on ActoGuitar.

Hope that makes sense.
