do you want to teach US or it's your Observetion ONLY??????????????

I honoured what you have said, but my friend I cleared one thing that do not USE links for forwarded domain any where.. AND A lot of Hosting provider Do not Allow .htaccess process in that case you...

I dont think 301 redirection is good solution.

The best way is Forwarding domain to main URL,

But remeber One thing, Never go for Link building process for Forwarded URL

Do not bother about number of indexed page unless your SERP not get flacuate. Give your effort to get more and more inbound link with proper Anchor Text

Great collection of SEO tool

good job
