How to tell if she's available? help!

Ask her. What else is the choice? Read her mind? Get real, will 'ya?!

yeah, forgot about my secret powers....

Are you interested in flirting with her or going out with her?

Flirting does not require the other person to be available. There is nothing in flirting past flirting.

that sucks. its harder that i thought...

Why is that so hard? If you want to date this woman, you will need to actually say a few words to her. How about if those words are, "Hi, I'm blue3232, and I couldn't help but to notice you. Are you free for coffee?"

and if you keep staring and do not talk turn off ?

Do you want to go out with her?

Anyone with half a brain will acknowledge your existence and will respond to you if spoken to (yes, even deaf people). Of course the answer could be no, but if you never ask, the answer will always be no.

If she doesn't acknowledge you when you speak to her, then she's nuts. Don't think another second about her. But that is a tiny minority. Most people weren't raised in a barn.

yes, that makes sense. i will try to say something next time. thanks for the answers guys !
