The mailing list for Icinga Users covers normal questions about how to install Icinga, how to use it in your day-to-day business or for getting help about specific problems or scenarios. Just become a member of this mailing list and start asking or answering questions by sending mail to email@example.com.
The icinga-devel mailing lists is your first choice if you would like to influence Icinga development in any way: If you want to share your ideas about future features, ask questions about a concrete implementation detail, offer your help or just want to know what is going to happen internally, sign up here at Sourceforge and send your mails to firstname.lastname@example.org.
The lists are more than happy to hear from you. But please note, that you have to become a member of the mailings lists, before you can start sending e-mail. Otherwise, the lists would be flooded with spam. However you can read the lists in the archives, without becoming a member first. Just click here for icinga-users and icinga-devel.
