Gamertag Checker?

[Chronos]

I have a crazy huge list of tags I'd like to check. There's too many for me to check them manually, it would probably take a few months. Anyone know of a program that you can load in a .txt file and it checks whether tags are available or not?

Don't think it exists lol...
And all the online tag checkers are stupid. I typed in the tag "Original" and it said it wasn't taken, i made a brand new account to figure out it was taken. -_-

This thread can be closed, I ended up getting Raigars Checker off HF, hopefully it works.
