OccupyPortlandWiki
I think "Welcome to OccupyPortlandWiki" will confuse people... to me it means that this is a wiki called "OccupyPortlandWiki", instead of PortlandWiki with a section of pages about Occupy Portland. So I changed it to "Welcome, Occupiers", which I think addresses the confusion issue but still intrigues anyone who's unfamiliar with Occupy Portland to click through "Occupiers" to learn what it's about. But maybe a different wording entirely would be better?
