I was doing a wizard quest and trying to purchase an item from a user shop. This strange message came up at the top of the screen saying this:

The site seems to be having issues if you use www.subeta.net rather than subeta.net. You seem to be using the www, so click here to switch!

It was in white letters with a black border around it. I've never seen it before. I didn't click on it and came here to the forums to make sure everything is okay :).

I'm using Windows XP and the newest Firefox browser.

That's actually pretty normal and goes back to the whole mess when we were not .net... Anyway, just click it and switch over, or better yet make sure that in your browser bar it does not say www. before things. Firefox has a habit of adding www. to everything, if I remember right... I use Chrome these days. It's totally safe.
