When I try to use the "Switch Account" "drop down" it just takes me to the page http://tulpanetwork.com/network/index.php (no drop down). I'm using the latest version of Firefox.

I am guessing you can't also click the "show unread posts since last visit" and "show new replies to your posts" links?

My theory: the banner is set at 100% width and your browser doesn't support Viewport to resize it to fit to you, so the banner link sort of goes on top of the links to the right even though it doesn't look like it's on top. It is a problem with older browsers and the one I like to use, unfrotunately, but I think the newest Firefox should support it? I would suggest you to double check if you have the latest version.

Why the banner is set up this way is so that people with even smaller monitors don't have the banner go on top of the links to the right, which was a problem earlier for some. Now it should be cut off before it happens, but if your browser doesn't support Viewport, this little problem rears its ugly head.

Also waffles already asked but I wrote you this tl;dr anyways. Correct me if I'm wrong, waffles.

Mind you, you can only click on the edge if you are using Headline theme. On CoalBlack, the position is different and it doesn't work.

We're (well, waffles really) playing around with this, but don't hold your breath.

I believe that with this one.
Of course, I usually find it very difficult to do this.

I don't think any spambot has managed to get through our security question either, all the spam accounts in the past after the question was put into use were guests.
