Yahoo! has officially announced that the Site Explorer tool is out of Beta. The two benefits of moving out of Beta are:

• Input URLs for Delete — You now have more flexibility. You can modify the URL or path you want to delete on the confirmation page.

• Delete more than five invalid URLs — Your limit has increased from five. Remember, as before, each delete can rid a whole path of URLs.

Now Site Explorer will support more features such as 'Report spam'. 'Now when exploring your authenticated site, if you find a suspicious inlink, such as an off-topic link or a suspected linkfarm, just click on the 'Report Spam' button and submit a spam report.'

Yahoo! Also offers mobile submit, “publishers can now submit mobile sites and feeds to Site Explorer, which enables them to get their mobile sites into Yahoo! oneSearch and gain access to Yahoo!'s mobile user base.”
