Changed Uncategorized to Discussion

Hi all. @kemitchell has blessed / cursed me with some admin powers so I’ve done my usual and renamed Uncategorized to Discussion.

Don’t worry too much about where to post, other than this #site-feedback category being the best place for meta discussion (features / functions of this Discourse forum) and feedback about the site in general :wink:

Kyle already covered this in Start topics, but basically Discussion is just that: asking questions and having a discussion about topics related to open source thriving.
