Emailed Author: There are issues with your code.
== Prefix your functions ==
In order to approve your plugin, you will need to make a few improvements.
Currently you have very generic function names that are likely to conflict with functions from other plugins or themes.
Every function in your plugin should be prefixed with a prefix that is unique to your plugin.
For example, if your plugin is called "Easy Custom Post Types", then you might prefix your functions with ecpt_{your function name here}.
== Calling files poorly ==
The way your plugin is referencing other files is not going to work with all setups of WordPress.
When you hardcode in paths, or assume that everyone has WordPress in the root of their domain, you cause anyone using 'Giving WordPress it's own directory' (a VERY common setup) to break.
Please review http://codex.wordpress.org/Determining_Plugin_and_Content_Directories and update your plugin accordingly. And don't worry about supporting WordPress 2.x or lower. We don't encourage it nor expect you to do so, so save yourself some time and energy.
== Your dashboard is an iframe ==
Having the admin dashboard be just an iframe isn't permitted.
We don't permit plugins to phone home like that (for two main reasons - security and appearance - too often people assume that they just signed into WORDPRESS and not your plugin). Please change your code to use an API or just link back to your site so they can configure things there.
When you've corrected your code, reply to this email with the updated code attached, or provide a link to the new code.
