Re: using PluginArticle to pull ONE full article ...
Dragon9874, no idea myself about your question. But you'd better send your question to the proper forum in http://tikiwiki.org/forums , or to tw.o sf.net lists, but not here, which is just for documentation issues.
Good luck, and welcome to Tikiwiki community.
And you'll be very welcome when you come back to help us improve the Documentation
Cheers
