Sgt.Slice-If the girl is even talking to you and she doesn't speak much english, then that tends to mean she's interested in you. The IOI's to look for in Euro chicks is the same as American...sitting close to you, asking you questions, her grabbing your crotch

, etc. One thing I say that works like gold is "You're crazy", in a C+F way. For some reason they respond to that. Again, same stuff works for approaching...walk up confidently, use an opener, grab her crotch

, etc. Just talk like it's just another normal conversation and make sure you're not afraid to smile...
Muse-Congrats on studying abroad! It's a fulfilling experience in which you are able to sample, firsthand, the many aspects of life that you will never see in the U.S.! Spanish helps ALOT, since there are a number of similiarities in the languages. I recently went to Espana and got along fine using Italian. If your college is in Florence or Rome, you'll get by just dandy. Just remember the basics and you'll do fine, but if you need any questions answered don't be afraid.
And just in case you guys are wondering, I've got just a wee bit of experience in Europe. I've been living here for over 5 years and am always glad to help out the wayward tourist. Have fun!
