Reality check

Did that. The "ignore" link doesn't go away when I click ignore. Instead it takes me to a page with only this thread on it. Clicking the blue star on this one-thread-page does not turn the star white.

This doesn't require scripting enabled, does it?

It works without javascript, but it's better with it. Regardless, the ignore button should work.

Should the ignore button change to "observe" immediately after you click it? It is definitely not doing that for me. I tried with Chromium also.

<not required reading> Chromium is what you use? ...or Chrome on Microsofties Windhoes? You don't have to answer that.

I guess I am the only one and this is just a big coincidence that it just happened to be the person who knows the sekrits of the RationalWiki voting machines. </not required reading>

If you have javascript, it should change to observe.

Oh, so it is different without scripts.

I found that they are appearing in the threads section of my watchlist, where I could remove one.
