Best way is to probably learn it using conventional methods. I.e. (id est :P don't you love it when stuff from Latin is still in use) books, school etc. Note that Latin is kind of a dead language so no people actually speak it anymore. Therefore you have to spend most time learning an extensive amount of grammar and reading ancient texts. I do agree that it doesn't seem like the most fun way to learn a language but I assure you that it's rather interesting. Here in the Netherlands we have the option to take Latin and Greek as extra subjects, but I don't know if the same applies to the American system. You might want to check it as I'm sure more people are interested in Latin and/or Greek. Greek is really interesting as well and I still regret dropping that one so I only learned Latin. Be sure to check it out. There's less grammar but unfortunately this means more exceptions. But, you can read parts from Homerus' Ilias in it's original language which really is priceless. Good luck finding a way to learn Latin! (And Greek perhaps...) P.s. The main problem with dead languages and a site like this is that there is no way you could use it in a conversation. We don't know how normal Roman people would've conducted conversations because we only have the stylized versions in the form of books, plays and stuff like that. (And as you may know, English people don't talk like the people in Shakespeare's plays, so that might give you a clue as to the way people speak in Latin texts.)

I know how you feel, I'm learning it as well but there's nothing on here. Two good alternatives would be "Cambridge latin course" from Amazon and the like or a podcast called "Latinum" .Both are very detaile and should help. good luck & carpe diem!
