Your WiFi encryption has nothing to do with that; I'm not familiar with Tails, but if astor's right (which he very nearly always is), then yes. Totally ignore it AS LONG AS you are on a .onion site.You MUST NOT ignore it if you aren't though. If you're on a non-".onion" site, the warning fully applies. That's very important, hence the caps, heh :) I take it you only get that message when you try to log in? Because otherwise something is very fishy, as you aren't actually transmitting anything except the request for a page when you just surf to the forums. I mean you shouldn't be, anyway, which is why it'd be fishy...
