Turn this off.
Both of it :D
I wanted to point out the 15 second rule is really annoying. I see it at least 25 times a day. And those useless links. Get it away, aargh!

The 15 second thing is nothing. I was once part of a forum (now defunct and offline) that made you wait 30 seconds between searches.

The only thing I miss about modding was I didn't get that damn 15 second rule then.

And the 200 pm spaces.

It's awful. After I read a topic I always hit 'new posts' to get back to the new posts. I don't want to click back and see the same postings again. But then I get this horrible window. So what I do now is click new posts, open all topics that are of interest to me by middle clicking the http://www.musicbanter.com/images/buttons/firstnew.gif button and then read the tabs, one by one. For those who don't know; Middle click = open in background tab.

My middle click is set to toss grenades. :(

What, in firefox? :D.
What's the use of that?

Well, I programmed the middle click to route to a particular key on my keyboard that throws grenades in Bad Company 2... and I'm too lazy to make another profile to switch between.

Will that matter, or does Firefox ignore keymaps?

I think firefox ign... wait, it's easier to just try it :D.

You must read really fast then :)

And the middle click thing would be useful if I had a mouse with 3 buttons. Or rather, if I had a mouse at all.

It opens in a new tab. Sweet. I never knew that.
But I have my options set so that any link I click (away from site) opens in a new tab, with focus set on that tab. This (middle click) rounds it out so that I can do that within the site. Usually I'd just right click and select it to open in a new tab.
