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]

Show Content by User Level

This simple plug-in hides content from all users except those that exceed a specific user level.

rexreed

This plug-in is quite simple: it hides content from all users except those at a specified user level.
Alternatively, you can think of it as only showing content to users at a specified user level.
Utilization is quite simple, with the use of the tag [hide {level}] and the end-tag [\hide] as the way to encapsulate the hidden content.
Future revisions will utilize Role Manager options instead of user levels, so stay tuned.
