You only need an email and 5 minutes to sign up to exchanges,it's more preferable to exchange in popular exchanges than creating a thread,you'll be force to send first since you are a buyer and your status is newbie which is a disadvantage.
But nothing wrong in trying to trade here in this market place for some extra bounty usually big whales love to give to newbies. Dealing here has another advantage of saving in exchanges fees. But, OP must deal only with reputed members otherwise he may end up in scam, in that case exchanges are fat better to deal with.
