 ==== Quotas ====
+/25/2011 Quotas have been enabled on cluster greentail.  Because group quota numbers are weird, it is like counting duplicates or following links or looping, not sure, we have to rely on individual quotas. Just as well.
+Here is what was put in place, and will mature over time.  But first, it is important to understand:
+  * A quota is not disk space allocated for you, as in reserved.  IT is simply a threshold (soft/low) that can be adjusted, or not.
+  * Reason for quotas: to avoid the /home to fill up by a runaway process, and constrain certain large users.
+The quotas fall into two tiers: the sliding tier and the custom tier.  In the sliding tier, when you reach your soft limit, notify HPC admins and your quota will slide to the next strata (<100G, <250G, <500G, <750G). Once you reach the last strata, and you still need more disk space, you enter the custom tier.  Here we set a quota after agreeing on size and availability of disk space, plus 100G.  Then you are on your own.
+We urge all users to consider archiving data and files off the cluster disk array.
+How to find my quota?
