Posterous is proud to announce the ability to change the look and feel of your Posterous blog! It's been a long time coming, and are we ever excited about releasing this feature to you guys today.

Choose from five built-in themes
Including one designed by theme creator Bill Israel. And we've got a whole ton more on the way. We wanted to get this in your hands ASAP, and we'll be releasing more into the system as soon as we create them.

Be able to upload header images
Customize your blog by creating a custom blog header in your favorite image editor. Then just upload it and see it at the top of every page on your blog. No coding experience necessary.

And choose new colors
Want to change the link color? Switch something up? Use our color picker and you don't have to code a single line of HTML.

For people who want to customize to the max...

If you're an advanced user, designer, or engineer, now you can totally change the CSS and HTML layout of your site.

Not only that, Posterous themes are similar in many ways to other blog themes made for the web. We built the Posterous Theme Engine to work great with the thousands of existing themes out there! Just drop the theme code into the "advanced mode" editor. Want to add commenting and favoriting? It's just a couple lines of simple HTML away. Read more about it in our theming docs.

Some examples of Posterous Themes in the wild...

Check out what Posterous super-themer Cory Watilo has built with full CSS / HTML customization:

Our friends at Mugasha, Vidly, and Tweetvite have all chosen Posterous to host their company startup blogs. Dustin Curtis is liveblogging his 30 day flight on JetBlue on posterous too!

So what are you waiting for? It's enabled on your Posterous blog now. Go to your Manage page, and click Edit Settings > Theme and Customize to get started.
