What if you have a site that was approved for google news, can you ad another site on webmaster tools as a channel that will show up on google news as well? or do you have to enter each site indivdually to google news submission?
If your website is fresh (New) then the regular process is to submit it to Google. However I never really had to do so, Google is smart enough to crawl your website if you have single incoming link. The more external incoming links you have, the more quickly you get indexed. The second most important thing is the structure of your website. It is a good idea to have a tree shaped page structure which will be easy to crawl by the search engines.
As I understand it you can add another site so long as it is considered a proper news source and that the xml sitemap uses the news format as opposed to the regular format. However I'll add that I am not as well versed in the Google news area so I could be wrong and hopefully someone else with more knowledge of Google news can answer this question more definitively.
You can try to use google webmasters tool. Verify your site and dubmit your sitemap and let you see few days ago
If you can spend more dollars you can get indexed your site within 24-48 hours. purchase link from high page rank website. I think it will be $100-200 or more. www.textlinkbrokers.com www.linkadage.com www.text-link-ads.com Just visit and give a try!
