This question came in via my email today, from a reader of my WordPress For Dummies book, regarding adding themes to a WordPress.Com blog ¹ :

How do I set up my wordpress.com blog to use your xMark theme? The setup instructions on the website say to send the xMark folder to the server, but that sounds like a wordpress.org setup. …. Recently I’ve tried again using the wordpress.com setup, and found that was more my speed. Now that my blog is up, http://dominickrusso.wordpress.com/ I’m trying to find a fluid theme, and that’s why I wanted to try xMark.

1. Management of themes on your WordPress.Com account is covered in WordPress For Dummies in Chapter 5. [↩]

Matt Mullenweg, of Automattic, announced at WordCamp Argentina that Automattic will soon launch a service for premium WordPress themes. The idea? To provide a repository of ‘premium’ WordPress themes for sale. Designers make 50% of the revenue from themes that sell - - Automattic pockets the other 50%.

It will be interesting to see if this kills the free WordPress theme offerings. From a designers standpoint - why continue offering up free themes when you can submit them to this WordPress Themes Marketplace and make a buck, or two.

And what will the going price be for these premium themes? Is it a standard price - for instance will it be a blanket price for all themes? If not, will Automattic valuate each theme? Based on what criteria? Or will the designer be allowed to set the price? Maybe it will be an auction-type setup where users can bid on the themes that are only sold once?

It’s true! However, unlike the service you’re using to blog on WordPress.com - customizing the theme is not free. At the time of this post, the current cost is $15.00 per year to obtain access to the Custom CSS feature on your WordPress.Com account.

WARNING: The WordPress.Com Custom CSS feature is not for the faint-at-heart. It does require knowledge of CSS in order to accomplish the task (or hire someone to accomplish it for you).

In your WordPress.Com administration panel, click the Upgrades tab in the top menu to access the place you need to be in order to purchase the option. Once done, you are granted access to the CSS editor and are able to edit the CSS to style your template the way you’d like.
