say my brand is 'T Shoes'

[webmasterbeta]

hi guys,

I was wondering:

say my brand is 'T Shoes'.
What is the best domain name to choose?
<!-- w --><a class="postlink" href="http://www.tshoes.com">www.tshoes.com</a><!-- w --> or <!-- w --><a class="postlink" href="http://www.t-shoes.com">www.t-shoes.com</a><!-- w -->

Is it possible to register with capitals?
Like <!-- w --><a class="postlink" href="http://www.T-shoes.com">www.T-shoes.com</a><!-- w -->

thx in advance!
