I want to eliminate blogs from other categories from showing up in the announcements category.
Also, can I alter the category that loads on the landing page?
Although your post doesn't make completely clear what you want, I suggest you read [url=http://manual.b2evolution.net/Stub_file]this topic in the manual about stub files.[/url]. With stubfiles you can exclude certain categories in the blog.
$blogroll_cat = ''; // This is the list of categories to restrict the blogroll to (cats will be displayed recursively)
// Example: $blogroll_cat = '4,6,7';
$blogroll_catsel = array( ); // This is the array if categories to restrict the blogroll to (non recursive)
// Example: $blogroll_catsel = array( 4, 6, 7 );
If you have a stub file for every blog you can manage the categories the way you want.
If you have any subsequent question, please do report back to this topic.
