The Kunena Birthday Module shows up the birthdays of your users. You can setup how much, how far in future to show. You can totally adjust the module after your wishes. You can create your own template for the module. How the string looks like you can change in the language file or with Joomla own overwrite feature.
You can choose between different user linkings: profile, mail or forum thread.
When you choose forum thread, it will automatically create a forum topic when a user have birthday with a predefined subject, category, botname and botid.
With the option mail it sends an e-mail instead creating a forum topic.
It works also with JS and CB. You can't use the module without Kunena (not yet)!
See github for changes.
