Unity 4.x - Limits of Distribution List members

Question

Is there a limit to how many members you can add to a public and/or private distribution list in Unity 4.2?

Hi Johnny,
Subscribers > Class of Service > Features Page 
Lists Available to Subscribers
Enter a number between one and 99 to specify the maximum number of private lists available to subscribers who are assigned to this COS. Subscribers can manage their private lists by phone and from the Cisco Unity Assistant.
Though both the Cisco Unity conversation and the Cisco Unity Assistant use this setting to determine when a subscriber has reached the maximum number of lists, consider that each application calculates the number of lists that a subscriber owns differently:
•When a subscriber tries to use the phone to create a new list by adding members, the Cisco Unity conversation counts the number of private lists that have members, and then compares the total to the value in this setting to determine whether the subscriber has reached the list limit. Lists with no members (empty lists) are not included in the total number of lists that a subscriber owns, even if the lists have recorded names and/or text names.
•When a subscriber tries to use the Cisco Unity Assistant to create a new list, the Cisco Unity Assistant counts the number of lists that have a recorded voice name, a text name or members, and then compares the total to the value in this setting to determine whether the subscriber has reached the list limit. Lists with no members are included in the total number as long as they have recorded names and/or text names.
This means that if a subscriber belongs to a class of service that allows 15 lists, and the subscriber has 12 private lists with members and two lists with recorded names but no members, the subscriber can potentially create more lists by phone than in the Cisco Unity Assistant before reaching the list limit:
•When the subscriber uses the Cisco Unity conversation, the subscriber will reach the list limit either by adding members to the two empty lists and creating one new list, or by creating three new lists. If the subscriber reaches the limit by creating three new lists, the subscriber cannot add members to the two empty lists until two lists are deleted.
•When the subscriber uses the Cisco Unity Assistant, the subscriber will reach the list limit by creating one new list. Despite reaching the list limit, the subscriber can add members to the two empty lists.
You can set up private lists for a subscriber on the applicable Subscribers > Subscribers > Private Lists page, though the subscriber is the only person who can send voice messages to the list.
Maximum Members Per List
Enter a number between one and 999 to specify the maximum number of members that subscribers can add to a private list when they use the Cisco Unity conversation or the Cisco Unity Assistant. (There is no limit imposed on the number of members that can be added to a private list when you use the Subscribers > Subscribers > Private Lists page to add members to a list.)
The subscriber is the only person who can send voice messages to the lis
