Make Announcements open to response

[Tim Gould]

I think that it might be a good idea to open Annoucements to responses. We've already got a place to make announcements that can't be responded to (on the website) and, many of the topics we've opened have to be duplicated elsewhere for further discussion (most recently by Travis).

I'm not saying anyone would be able to start a topic there, but I do think allowing responses would be a good thing.
