Apparently there is a bit of nasty malware virus spreading through the social networking sites, including LiveJournal. It targets communities, generating a mod-ish looking post informing the membership that the community is being closed, and then deletes all the community's entries. The post includes a couple of links which, when clicked, will infect the clickee, compromising their personal info as well as their f-list.
So...please be aware that THIS COMMUNITY IS NOT CLOSING. If you see such a post, do NOT click any of the internal links. Please DO report the post to LJSupport by clicking the red flag icon or the "flag" link, depending upon your viewing option. This warning is site-wide, so please keep this in mind if you encounter strange so-called administrative messages on other communities of which you are a part.
