On the NETTUTS.com blog today there's a new post that includes a list of sixteen things you need to be sure to check before releasing your WordPress theme.

Releasing a WordPress theme on a marketplace, such as ThemeForest, where the audience is so large and diverse, has some challenges. You cannot test a solution directly with the client. You need to plan in advance for all edge cases, and ensure that your theme is as customizable as possible. If you're inexperienced, chances are that some things will unfortunately slip through the cracks. Luckily for you, we have drawn on our hard-earned wisdom to help you avoid repeating the same mistakes we made.

Among the things they suggest checking are things like:

• Don't Display Comments on Protected Posts
• Introduce Right-To-Left Support
• Make Paginated Entries Work
• Do not Forget wp_footer() and wp_head()
• Support Custom Menus
• Make User-Visible Strings Translatable

Each item on the list comes complete with a description and code (when it's needed).
