Bitte schön, knowone.
You can usually get the gist of what is going on in a foreign-language scuba forum thread by running the text through Google Translate. The fact that the subject matter - diving - is familiar, shared, territory can be a big help when trying to bridge the gaps that Google leaves behind. I happen to know German because I've studied the language, but I've often used the tool to render into English scuba blogs and threads in Chinese and Japanese, languages which I don't know. The results aren't always elegant, but I can usually work out what the writer is saying and, an added interest for me, I also get a little insight into how Far Eastern languages function as well as some understanding of the culture underlying them.
I'm hoping that "Eins" ("one" in German) lives up to his/her user name and knows enough German to benefit from reading German scuba forums.
