Media Limits (module jrUserLimit) sets how many times a day users in a quota can stream or download each kind of media. For example: 20 audio streams a day for free members, unlimited for paying ones. The limits apply to the user doing the playing, not the profile the media belongs to. Master and profile admins aren't limited.

On the Quota Limits Config tab, choose:
Add one limit for each combination you need. To limit how many items profiles can create each day, see Daily Limits. For monthly limits per IP address, see Play Control.
