You can kind of think of this as a public email account. You post
things for discussion, everyone can see them and reply to them. Alot
like the comments section on the blog, cept that this is broken up
into threads (discussions) and you get notified (emailed) when
somebody replies to a discussion you started. Hopefully we can do
something like what Heidi is wanting to do, create topics so that the
discussion threads can go into the topics, just like on the main site.
