I like the little triangular banners you can put in the top corners of your website and blog. I’ve decided I would start a post collecting those. Since I couldn’t find a lot I’ll start with a couple and encourage people to make more for the websites (particularly humanitarian and non-profits) that you like.
Let’s be advocates through our blogs.
You can read about how to put this banner on your site here.
If you want this banner for your website (and get it to show up for just Internet Explorer users) then check this out.
