qustion about permission component use

Hi, I would buy your component but I have a question (I tried to use the demo but I did not understand enough).
I would need to create various registered users.
For each registered user will create an article.
Each registered user should be able to change only the tags of his article, and not those of others.
is it possible?
Thank's for support

It could be done:
- make your registered users member of the 'Author' user group*, so that they can only edit their own articles
- Authors are able to assign/edit tags only from the frontend, when editing their articles.
- Because of the way Custom Properties works, they'll be able to choose only from the set of tags that has been created from the backend inteface by some admin.

* see here docs.joomla.org/J3.2:Access_Control_List_Tutorial for an in depth explanation of Joomla 3 ACL

Hi, thank'u for the feedback!
First, sorry for my terible english, I you want I can write in italian
Ok, I know with the joomla acl I can create an article for author, but i would this author can edit ONLY tags and not the content..
In your demo I see registered users can click on "edit tags", and change tags with custom properties interface, without have access to full edit interface of article.. but they can do so on all articles, while I would like that each author could only do so on his article.
In other words, an author = an article = ability to change only tags (and not the content) of this articles and not the other articles..

The current package does not support fine grained frontend-taggin permissions.
You can enable/disable such functionality for a given user group (even custom ones).

Hi, thank you.
Now I try to reason with the proposed system (users with author access privileges).
I have do some test in your demo.

1. i've create a user with author access

2 I've create an article and assigned it to this user

3. now this user, in the frontend, can edit only this article

BUT

You wrote:
"Because of the way Custom Properties works, they'll be able to choose only from the set of tags that has been created from the backend inteface by some admin."

When I try to edit in the frontend this article, where I can see the set of tags disposed in the backend? I can see only the standard joomla tags system.
I thought I could see the form of the choice of tags on the style of custom properties, I'm doing something wrong?

thanks for your support and for your patience!
