WP JV Post Reading Groups

Thank you. Your work really saved me a lot of time. Thanks again

Very good

Easily create posts and pages visible only for selected users of your blog

This plug-in hides a specific part of the content of a page (or post) to all users whose user level is below a required user level.
Therefore, if a content is visible to user level X: 
1. if X > 0 users who are not registered will not be able to access that specific content; 
2. users whose user level is less than X will not be able to access that specific content; 
3. users whose user level is equal or greater than X will be able to access that specific content.
To hide a specific content, use the following syntax to encapsulate the hidden content: 
[hide {level}] {content} [hide {level}] 
where {level} is the NUMBER corresponding to the user level, and {content} is the part of you want to hide.
Example: 
[hide 0] You will always see this content [hide 0] 
[hide 1] You will not see this if you are not logged as subscriber [hide 1] 
[hide 2] You will not see this if you are not logged as contributor [hide 2] 
[hide 3] You will not see this if you are not logged as author [hide 3] 
[hide 4] You will not see this if you are not logged as editor [hide 4] 
[hide 5] You will not see this if you are not logged as administrator [hide 5]
Fancy example:
[hide 1] You will see this if you are logged as subscriber [hide 5], but you will not see this if you are not logged as administrator [hide 5][hide 1]
