Don't know, tell me

I like a lot a domain name, but it's taken (although expired). Let's call it X.com . I own another domain G.net . Will be legal create a site X.G.net , I mean a subdomain of my domain G, that has the name of a domain that someone else owns. If I can do it, will be correct use the X name as title. With what name I have to submit it at all the search engines. Please give me your advice. It's really imortant for me. Thanks.

This is confusing, so you want a site named "microsoft", the domain microsoft.com is exipired. You want to create a subdomain of you domain yahoo.net, so microsoft.yahoo.net.
You question is "With what name I have to submit it at all the search engines". Names don't really matter, but you shouldn't give microsoft.com as your URL, because they won't find microsoft.yahoo.net.

Yes that's exactly what I want, although it's not about a such known domain as microsft. So, I can create without troubles and promote a site like : microsoft.yahoo.net and use as title "microsoft by yahoo.net" on my site and also sumbit it with this title, with my URL of course. Really thanks. If you'd like just confirm that this is right.
