    Sepp, penalties with green asterisk are "advanced" and hidden by default.
    did you see "Show advanced" or similar button on the form? Press it and you will see all settings.

    Sorry, no such button. Some of green-asterisk-entries are visible, e.g. :
    -Penalty for misplaced token
    -Maximum percent of mistakes

    Thanks, Sepp. Two penalties was really disappeared from the question editing screen during internal refactoring. A placed a new version there (2.6.1.) that should make them visible, please try it.
    The button now called "show more".

    Thank you. Now it works! I can set the penalty for missing token.

    But, ... smile
    not every token is as important as each of the others. Is it possible to add an indiviual missing penalty in the description token window? eg. separated by ~
    for: for command~10%
    ( : bracket~5%
    int : data type~20%
    and so on

    Is there a possibility to use another language istead of english (I do not mean C/C++ etc.) - german for example?

    It's depends on the language (or words used in answer to particular question). CorrectWriting use language to tokenize input - i.e. break answer down to the tokens - words, punctuation marks etc. That may not be always intuitive (cf. single apostrophe in English at the end of the word which can be a quote or a part of word). If the rules of tokenizing German (for you answers) are identical with English you can just use English in the question. If not, that will require some additional coding either from you or from us. I would expect problems with German letters that absent in English, I do not know about other details of German.

    We can be contacted about developing support for other languages, thought considering other tasks we can't guarantee to do it fast. Thought if you are researcher, there are ways to motivate us to work faster under support of some language.

    These type of tool are really so needed while writing to ensure that your content are error free especially if you’re the type that can hardly spot out errors on your writing.

    I am using this plugin as a sentence checker and improved my grammar as a writers to writing service.

    All Best!

    Very clever plugin! Helps me a lot especially when I'm i a hurry and letters appear in a jumble.
    But the real brain is still the best grammar checker and unfortunately even it makes mistakes. And writing tons of papers and essays for students in customwritings review center this plugin is a great help.
    If there is a German language checker it will be priceless. Hope you'll add additional coding from your side.

    Thanks for this very helpful plugin. We're going to use it for English as is but we have other languages we would like to use it with, say French, Spanish or German. As is, the tokenizer for English cuts on every accented character which renders the generated tokens unusable. Would it be possible to integrate a more relaxed tokenizer as an option. We would also like to be able to use your plugin for exercises about phonetic transcriptions. The IPA alphabet uses the standard characters plus a specific table in the Unicode space. Rather than making a complex tokenizer for each and every case, would it be possible to allow question writers to tokenize manually?

    Grammar is the most important part of writing and it is a big issue for students when they are trying to write an essay or assignment in English. Now they are taking online dissertation help UK for improving their skills and obtain good marks.

    Not so long ago, essay writing required many hours of sitting in a library, studying multiple sources of information, and then rewriting the text by hand. Now, of course, the task is facilitated by the ability to find information on the Internet and just copying it, but to look for this information, and structuring and proofreading text, still takes time. In addition, considering the abundance of data on the worldwide web, you can’t always be sure of information's authenticity.
