| | 4 | + * NewUsersList parser hook extension -- adds <newusers> parser tag to retrieve |
| | 5 | + * the list of new users and their avatars. |
| | 6 | + * Requires SocialProfile extension in order to work correctly. |
| | 7 | + * Works with NewSignupPage extension, i.e. if the user_register_track DB table |
| | 8 | + * is present, this extension queries that table, but if it's not, then the |
| | 9 | + * core logging table is used instead. |
