You must be trolling as they all work fine for me. Try ripplewise.com
I guess you missed the bit on the logo which reads 'Beta'.
No not trolling, just describing my experience
First I Googled Ripple Exchanges, seriously not a single link was a ripple exchange
After literally fifteen minutes drilling through
www.ripple.com finally found their exchange link with 7 links, 4 not in english. 683admin.com not working, xrptrader.com not working, technocashier has no obvious way to create an account. So that leaves justcoin and ripple wise that use English, which does not increase the confidence of someone that wants to drop $5k on Ripple.
Also, justcoin also was overly simplistic and wanted to charge me 3.5 cents per ripple, much more than their site even listed trades for. Then read the bottom of ripplewise.com web page, confidence tanked....
So if I am trolling it would be that I do not understand how can an effort backed by so many big names stinks so bad, BETA??? terrible excuse. Google's worst Beta blows away everything i have seen surrounding ripple to date. Ripple is right now not trying to sell RXP IMHO, they are doing something else..... because buying RXP is terrible.
That said, I would still buy some ripple today if I could get my confidence up in one of their sights that uses English.
earlier u could buy at Bistamp. And there is Justcoin. That is a Ripple Gateway.
