I am looking into Ripple because the exchange rate looks more stabile than Bitcoin. I registered but how can I get Ripples? It seems that in order to buy Ripples you need at least a certain amount of Ripples but I don't have any Ripples because I just started out. There is a link in my Ripples wallet to https://bitcointalk.org/index.php?topic=145506  but I don't seem to be eligible for this.
