don't be shy, or do you suspect it might be too usefull? ;-) I found
it funny, so it must be good enough.
here my remarks:

[what's bad about non-alphabetic characters?]

oops: this function gets an argument s, here you're using the global
variable userstring. I know, it works, but there will be functions
were mistakes like this weren't just ugly but buggy.

or easier (much more readable, helps understanding the programm):
for char in s1:
if char in string.ascii_lowercase:
s2 += char
