In Resources/Centers you can view a complete list of centers related to Sound and Music Computing ordered by country and a link of them.

You can crete new one at Create Content->Research Center.

But there is more information stored in the database, now just for showing you statistics. Some information is outdated, so if you want to appear the real statistics ask us about adding permissions to edit your center. 

When having permissions the 'Edit' link will appear next to your center so you can add statistics and appear in the graphics.

The screenshot of the editing page is attached.
