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.
