We would like to ability for a project lead to moderate comments entered by users in a customer visible issue/project. We are investigating the possibility of letting our customers into the system and the main concern is that some grad would blab his mouth off about something about which we would really rather the customer was not aware. Having some ability for the project lead to moderate all potentially customer visible comments would go a long way to convincing the powers that be in my company that JIRA is a feasible platform for customer visible issue tracking.

All that aside - keep up the good work! Great product.
