Following up on the discussion in mozilla.support.planning about what kind of content we should support on SUMO (and by extension the scope of the Knowledge Base), ...
My thoughts on these articles and their appropriateness for MDC:
Editing configuration files: not really appropriate for MDC.
Profile folder contents: This one is borderline, but I think would be a good addition to MDC.
Command line arguments: Definitely should be on MDC.
Plugin scanning: Doesn't belong on MDC.
Running different versions of Firefox at the same time: Belongs on MDC.
