If in doubt, don't That's how I usually see it anyway. Generally speaking, if you're asking for opinions on a site you found, or wanting to share another site that you found and think others might enjoy, it's probably ok. If it's blatant advertising for another site, then you need to clear that with an admin first. Between the two is where it gets confusing, and I admit that I usually stay on the side of "don't" unless there's a very good reason for it. Hope that clears it up a little!
