Have you seen many photos of her and more so, have you seen her on webcam? A lot of people who aren't genuine & try to scam people use photos of other people + won't chat on webcam (some are even guys mascerading as women!). I'd feel a bit less worried with sending anything to someone that I'vd chatted to on webcam and seen many photos of rather than someone who I haven't. I still wouldn't send and largish amounts of money to someone that I'd known for such a short time though.
But if you only send a small amount or even nothing, like tuft says, if she sticks around and carries on being as friendly without giving any warning signs or asking for much more, then she is more likely to be genuine.
