Перевод - Английский-Японский - Translators-linguistic-knowledge

I think


Cucumisとは翻訳者のコミュニティであり、
メンバーが自分の技能を提供して助け合うオンラインサービスです。[/b]

互いに is not needed,because 合う of verb 助け means
"help each other". 互いに助け合う sounds like "help each other each other" in english.

Ian, could you check this translation and Mikhail's input.
Thanks

Original Translation before edits:
「Cucumis」とは翻訳者のコミュニティ、メンバーが自分の技能を提供し、お互いに助け合うオンラインサービスです
Notes:
Mihail's grammatical addition ("de ari" ) sounded better to me, too.
As for the phrase used to translate "help each other", the translator's version sounded all right to me, but just to make sure, I Googled it as a phrase (in "quotation marks", so it wouldn't get searched for in pieces), and it came up with 197,000+ hits, so obviously some other Japanese people consider it to not be too redundant to use...
On the other hand, "linguistic knowledge" had simply been translated with a very general word meaning "ability" (in spite of the fact that the exact term for "linguistic knowledge" is also used in Japanese): this was corrected.

This is indeed a better translation (であり、　言語知識). As for the redundancy, i don't know as it is indeed (mis?)used quite often here.
