Revise my English translation

Most of you recognize that English is not my native language when using Looking4Cache. I give my best to provide a proper translation, but I think this will not satisfy a native speaker.

And that is way I ask you to help me if you are a good English speaker. I created a webpage where you can view and revise my own translation.

The translation page: translate.looking4cache.com
A short manual: Manual

Thanks for all your help!
