CiaKKi,
I'm sorry to hear that the page didn't load. I look at the analytics for the wiki on most days, and it shows an average of one hundred views per day, so poeple must be getting through. However, there could be still be a problem with the server.
Wikispaces should be pretty robust, but this one screencast was put on my own ISP server which is Comcast (they have had problems lately). I wanted to put it up on youTube, but it was too long. Perhaps, I'll provide an alternate link to my public drop-box area - they have been pretty reliable so far.
Thank you for letting me know about the problem, and I hope you have better luck in the future.
