I have successfully install 3.0 multisite. At first encounter problem with error 500 and 404 pages. For those having this problem most probably related to htacess file.
Anyway, I need to display all my subdomain site categories and postings into central location at the main installation.
For example, i have a site, let'say, http://www.abc.com and 2 subdomain sites with 123.abc.com and 789.abc.com. 123.abc.com has two categories with 5 postings and 789.abc.com has 3 categories with 3 postings.
How can i display all the categories and all postings under the those categories automatically in main site ie. http://www.abc.com
