Hi,
I've found great exchange platform, CoinDeal. It has just started, so fees are lower and you can be part of the new community. Also, affiliate program works, so you can invite your friends and get part of their fees.

Bitcoin.com is just one domain name used to promote Bitcoin. Bitcoin.com is not an official website. Just like nobody owns the email technology, nobody owns the Bitcoin network.
As such, nobody can speak with authority in the name of Bitcoin.
