For reference (raised by rozzin in IRC): * http://foldoc.org/module * http://foldoc.org/library * http://foldoc.org/plugin As noted by XRevan86, modules are not necessarily non-essential. As we will keep the modules directory in GS root [therefore, near to plugins/], it is evidenced the difference between both. This is a simple yet fundamental structural change. It doesn't change functionality but makes clearer the way we understand GNU social's internals.
This is an additional plugin which piggybacks on OpenID authentication to pull profile information from WikiHow user pages when creating or updating accounts. WikiHow runs a customized MediaWiki setup, with locally-built extensions to add profile features such as an avatar. As this additional info isn't yet exposed through OpenID, we need to pull it separately.
