I am planning to create one module to display announcement for user of web site.
While the announcement module must be keep showing and then it is also can be programmatically set the visibility of the other module on that page.
For example, users from United Kingdom, United States, and Canada can be only read the announcement and the content of that page which is including other modules (can be more than 2 modules at that page, right?)
At the other hand, visitors who are not from 3 countries mentioned above will only able to read the announcement module, but cannot read other content of that page like other modules must be invisible.
Anyone know how to control or setting the other modules to be visibility?
