We are fond of the request indexing feature of Google Webmaster. But since it has been disabled users cant manually request indexing. However google has stated that it is only for temporarily basis and will be up after the updates are incorporated.
Google said on this that pages will be crawled automatically by the search engine, its just that manual submission has been disabled by the system till further notice. So far there is no update from Google as to when will this be live again.
We will keep you posted as soon as we have some update on it.
