We have a mailing list for Hedgehog. It is used for announcements of new versions, for reporting bugs, questions and general discussion about Hedgehog. To subscribe, send mail with any subject and content to hedgehog-subscribe@hedgehog.oliotalo.fi. You will get an automatic response that asks you to confirm that you really want to subscribe. The purpose of this two-step subscription is to prevent people being subscribed against their will.
To unsubscribe, send mail to hedgehog-unsubscribe@hedgehog.oliotalo.fi.
The list archives are updated about every fifteen minutes. To reduce spam to the list, it is moderated for non-subscribers. This means that one of the moderators needs to manually approve mails that are not sent from addresses that are subscribed to the list.
The list is protected by a spam filter that occasionally makes mistakes. If you have trouble reaching the list, please mail liw@iki.fi and say "Hedgehog" in the subject.
