PS: This is NOT a criticism, but I understand that English is not your native language. The manual has a lot of errors particularly with grammar. I would be happy to assist you in rewriting it correctly and to proof-read any other documents you wish to produce for the future.
This is not a problem, we had testers suggesting several fixes to the manual grammar, but apparently it's not yet perfect. Sometimes though, I short sentences just to make them fit a specific page layout without having to reformat everything...
In any case, just PM me with the most obvious things you would like to correct.
