I'm happy that all of you can meet each other and exchange languages! But be careful putting your email publicly on sites like this. Others can read them and they can be picked up by spam bots. Its better to write
name (at) domain (dot) com, for example, koreyc (at) bgsu (dot) edu
That way the spam bots can‘t pick them up and send you 垃圾
Good luck with your Chinese studies!
