For creators that are making updates for their members each month it would be good to have option that membership renews at 1st of new month or exact date instead of after 30days. To avoid some users manipulating their membership on purpose in order to get 2 months updates for same price that others have only 1 month update. Of course users have to be notified about it during process of getting membership so they know how long will their memebrship last.
