Blueprint?

So, I clicked on 'last post' on some topic in here, and found myself logged out. Having only logged in about 5 minutes earlier. Hey ho. But that's not all, I was staring at a screen that told me I was in a forum called 'Blueprint'. Never heard of that before.

Anyway, I clicked Log In/Register and without being taken to the log-in screen or doing anything else, I was logged back in. But I was still in the Blueprint forum.

No wonder lost souls turn up.
