I am registering a domain and I do not know what extension I should buy for my domain. The pre-extension stuff is 5 characters long. (Not saying what it is so not trolls reserve the domain) The .com, .net, .org, and .info are taken. I am willing to get the .us, .biz and .me. Personally, I want to get the .US domain. Maybe, it's because they are cheap or because it makes the domain super short or whatever. I still wasn't sure, so what domain extension should I get/do you recommend?
(Suggest some more extensions if you like! :D)
