PixoPoint Google Calendar
Sorry, but there are better ways to do this now. This project has been deprecated and is no longer in development. This page will be kept online for archival purposes and in case anyone is still interested in the project despite being no longer maintained.
The PixoPoint Google Calendar plugin for WordPress allows you to simply copy and paste the embed code from the Google Calendar service and it will be automagically converted into a WordPress shortcode for you. This makes it ideal for use on WordPress Multisite setups where the use of embed codes is not allowed due to security concerns.
