Hi,

Is there any way to enable a control changes when I am reviewing a topic?

I was looking for something similar to Microsoft office word, to enable do reviews by several members of a team and after taht the owner of the documentation review the changes and accept it or deny.

I do not want to set up a control version system, only a way to do a review previous to release a documentation.

 Thanks,

Community Extensions is ideally suited to this. Users / business stakeholders can record comments and feedback from directly within the generated help system and you as the author can easily review a list of comments using Tools\Community Content within HelpStudio.

You can find more info about Community Extensions here:

.. and there is a section in the online help describing how you enable it from HelpStudio. Let me know if you have any problems.
