Oh and quick tip. To make your website show a link preview in discourse, make sure you include these metadata to the <head> section of your site. It will then show up when people use your link, like me.
e.g.
<meta property="og:title" content="Designing Open Democracy">
<meta property="og:type" content="website">
<meta property="og:url" content="http://designingopendemocracy.com">
<meta property="og:description" content="This is a group for any tech professionals or political experts (or ordinary citizens) interested in discussing in a detailed way the potential opportunities for reforming existing democratic institutions; from local organisations to national governments around the world through technology or other practices. Our aim is to improve democracy: we think this can best be done by providing a forum for discussing democracy proposals, ideas, and to foster collaboration between people who would like to participate in democracy reform.">

This will be especially important when you make campaign websites that would be shared by links. Especially if shared in facebook or twitter etc…
