If you hadn't already seen the blog entry done by The Madcap Laughs, let me direct you to it. Yes, Anonymous is going to be protesting outside the various cult centres of the CoS on February 10th, thats exactly one week from today.
Personally, I'm not taking part, because of aforementioned money troubles, and because the other people who I know who are going will likely try and drag me into a pub crawl afterwards - and I absolutely have to be up early the next day. But I'll be lending a hand to the Edinburgh protesters and will be there electronically, if not physically.
Also, since I like Anonymous and don't like the CoS, I've been trying to spread the word among various Discordian groups as well. As far as I know, there will be Discordians showing up at New York, Portland, Edinburgh, Melbourne and London, to give a helping hand. Probably some in other areas as well, but I only know so many people.
Anyway, if you want a definitive list of CoS centres that are going to be protested at, go here. So, if you happen to be free on the day, and are near one, go give a helping hand (mindful of the dress code, however). Its a good cause, after all....
