one deffinite one is when you see them looking at you and you turn to look back at them, they turn away smiling to themselves.

Well,I'd definately say smiling and looking away is a sign,also getting as close to you as possible,and finding every reason/chance they get to brush up against or touch you.It's also in the tone of their voice,you will just know.

if they hold your gaze for a few seconds, then look down and look back up and smile its usually a sign they like you, or they have wind :) haha.

I read into signs all the time. It makes me quote from a radiohead song:

"....just coz you feel it, doesn't mean it's there."

Sometimes this is true. Sometimes this is not. Depends.

I used to look at my own personal issue regarding reading THE SIGNS with trepedation and melancholy. Now I have to look at the humor of the situation. Sometimes I often wonder if we're both playing a game or a dance, knowing how forbidden it is if either one of us makes the next move. It's a game that will always end in a draw...Better to have taken the risk then not to have done so at all :)

I'm really interested to hear what other people say about THE SIGNS...
I've noticed lately someone at work looking at me but I try to act aloof. I then even stare down too. Hell, I'm not pursuing anyone, that isn't the direction i'm heading. It's just interesting what options life has to offer :)
