This is only necessary if you are not using the RedMystic Core Module but still want to manually send your products to RedMystic and optionally Google Base.

Add this meta-tag between the head tags in your template : 

<meta name="redmystic" content="12345AnExampleSiteKey" />

Replace 12345AnExampleSiteKey with the site key provided by RedMystic. If you do not have one then you must login and register your site to RedMystic. Once logged into RedMystic you will find a register site menu item on the left side.

In the Redmystic component , navigate to the product monitor tab and hit the "notify RedMystic" button.  You will have to click this button each time you want to submit your products.

Of course there is a much easier way! Just install & publish the module and it'll take care of the meta-tag and product update notifications to the RedMystic server. It is designed to monitor your products for changes and to notify the RedMystic server of those changes.  It provides you the freedom of not having to remember to submit your feed each month. (Remember Google and Redmystic products expire after 30 days).
