If I don't have a web cam can I still use skype?

yes you will be able to use skype without webcamera. just download it and install it into your pc. you'll be able to use skype but you can't make vedio call.other things you can do. if you make a vedio call,your friend can not see you. but vedio call can be given.
note that if your friend doesn't have wbcamera too, both of you can not see each other.
to see each other, you should have webcamera, but without it you can make vedio call but you will not see each other. if your friend has a webcamera you can see hm/her.
