A guestbook has been added to the website. Of course powered by a Horde application.I just added a very simple guestbook to the website, but that's what guestbooks are, no? It's powered by Volos, one of the younger Horde applications.
I'm still not sure if this module or rather Mnemo, our notebook (as in notes, not laptop) application, should provide comment capabilities to the other Horde modules in the future. I think of allowing comments to news stories/blog entries or adding notes to email messages in IMP.
