There is a slight mention of the shut-down in the list of issues released. It notes that i24 won't be coming out, but really not much beyond that.
Yeah, we need to be there, including the petition link.
A link to the petition isn't the kind of thing Wikipedia would want as a source. They're an encyclopedia, not a news site (Wikinews is for news, although they also have notability standards) and while this is important to us in our circle, we'd need to be able to demonstrate the significance of our actions as they might pertain to the gaming industry or activism in general. We likely won't meet such a requirement until we actually effect a change, and by the time we do that the source that Wikipedia would like is a news article referencing the petition rather than the petition itself.
Keep in mind that Wikipedia articles are supposed to provide a neutral point of view and cite sources (and not primary sources, with few exceptions). While news articles are a secondary source, we have to be careful not to get slapped with a reminder that
Wikipedia is not for news reports.
Someone's already added the basic facts of the termination to the opening of the article, and a couple of reputable news sites are cited in the Production History section regarding efforts to save CoH. We should keep an eye on it, but I don't think there's much more we should do on Wikipedia.
Addendum: In fact, some Wikipedians are watching the page and even put in a request to protect the page against vandalism. You can check out the Talk page for the CoH article, towards the bottom, for more details.
Wikinews, on the other hand, could be an outlet for us to cover major developments. When we've got something we want covered it might be best to contact an active journalist on Wikinews to write it for us, to avoid having an article written by one of us disqualified.
