It usually means an air test to check for Ozone. (check out Zot in the Lexicon) Newbies are almost always suspected of being trolls, especially when they say someing considered to be a little 'inflamatory'. Curious posters may look at prior posts from said newbie to see what their posting history looks like. Most often it is nothing, however sometimes the newbie's troll status is confirmed, and the Viking Kitties inevitiably show up...
No worries, if you're not hear merely to cause trouble, you won't get the Zot.
