send cat facts to your friends logged into a ews/server. netid = username if you're not from uiuc

# why did i spend so much time on this.
# this got me banned from the school servers for two days

Better use split() instead of split(' ') in line 34. My version of who separates the columns by multiple spaces, so split(' ')[1] returns ''.

But nevertheless, thanks for implementing this 😄
