There still seem to be some problems, though ...
- http://www.sunpoker.com/de/promotions/promotions.asp gives you some strange language description of "one sick bonus" (btw the tab "promotions" probably would be more adequately named "BONUSAKTIONEN")
- the "Bankwesen" tab gives you pictures with English phrases "Fund With Neteller" (and the name of the tab should be something like "EINZAHLUNGSSICHERHEIT", "SICHERE TRANSAKTIONEN" or "EINFACH EIN/AUSZAHLEN")
- the main page has the same caption for the bad beat bonus and the refer a friend one ... you're not seriously telling your players that your bad beat bonus is a whopping 25 bucks, are you?
Plus, it should be "Einem Freund empfehlen" in stead of "Einen Freund empfehlen" (the former meaning "recommend to a friend", the latter "recommend a friend")
(just listing a few here that I found surfing your site for 5mins or so)
all in all the translation seems to be OK but doesn't sound quite right to a native speaker ... especially the testimonial gives me the creeps because it is very incoherent.
I sure do appreciate the localization, but right now I'll keep sending my German traffic to your English site because your German site will probably convert pretty badly - anybody reading this will doubt your integrity which obviously is the opposite of what you're trying to accomplish here.
sorry if this seems like a lot of criticism for one posting, but I really feel you could (and should) do much better.
