I'm unsure if a community can be built around a product such as the Re, but, in my experience, nothing kills that possibilty more quickly than forums that aren't easily navigable.

I think most people expect the newest threads to be at the top of a forum and those threads that have new responses to be bumped up the list as well.

This may not be a dire situation, given that most people who do post here will do so for a few days and never come back again, however, if this site ever gets a large number of posts, it could get messy enough to deter someone from ever posting at all.

I've changed them so that the newest topics are now on top.
