Don't ask her if you can meet her again, tell her you'll be on skype again at such and such a time and ask her to meet you on skype then. Don't say can I skype again soon.
Play it by ear when you ask her to meet up. If it's going well then make it sooner rather then later. i'd not ask after one skype in though. I think I'd be too soon if it was me.
It's going well so far. Take it one contact at a time and no expectations or investing emotionally too soon.
