Can I use Confluence without an internet connection? (trial user here)

[Steve Loman]

Could I post messages that send next time I connect?

No, it doesn't really have an offline component.

I tend to write pages up in a text editor and paste them in next time I'm online, or do basic word processed docs and use the word import.  Some people have implemented "page create by email" type tricks as well (so emails upload next time you connect and generate pages)

You might also want to check out the "road runner" addon for it, which is a bit more sophisticated (I've tried it briefly, and it seemed to do what it said, but I didn't spend long with it).  I don't think there are any other addons around that do the same as it either.
