June 2011 Yes you can play Club Penguin if your membership runs out, but you can't use you upgraded igloo or get other member items out of store. You do keep your puffles and can use them, however you aren't able to get more or replace them if they run back to the wild. If you buy membership again you get all your Items back.
you cant really do anything you cant wear your cloths anymore and you don't get money or have any member qualities
When your membership expires, you cant keep your igloo or wear any member clothes. The only thing you keep is member puffles. It doesn't go away but you get it back once you renew membership.

A 'SWF' is a flash-file. Flash is the program that runs Club Penguin. If you decompile Club Penguin, you'll find SWF-files, like rooms and catalogs.
