hello, how to manage new added sites (I mean the sites of which I did not ask to index, there is the ability to selectively add the founded sites) ?

-- new founded sites manage

Under Manage Crawls, if you choose options. You can specify allowed to crawl urls and domains as well as disallowed to crawl domains and urls. Details can be found at: https://www.seekquarry.com/p/Documentation#Performing%20and%20Managing%20Crawls (look for the image with Edit Crawl Options)
