Where the discussion is about the content of an article, then yes the discussion pages are definitely the right place...

This section is more of an open forum for discussing processes, conventions and ideas on the wiki in general rather than specific content. As such I think Ken has a point.

Ken feel free to recommend conventions etc... I think most of us are fairly new to wikis and mediawiki in particular.

out of this free form discussion, firm conventions can be defined, approved and implemented. :)
