+Managed Postings Forums
+
+The concept of managed postings is very simple. Users
+will be blocked from posting after a given number
+of posts in a given period, and as they approach
+ that number, they'll be warned that they are
+approaching the threshold.
+
+Setting either the warn threshold to 0 will disable warnings,
+and setting the block threshhold to 0 will disable blocking.
+If blocking is disabled, warnings will automatically be disabled.
+
+None of these settings affect teachers posting
