[GLLUG] Re: linux-user digest, Vol 1 #883 - 2 msgs

Jess

This girl who went to my home church who goes to MSU now.  She is really nice.  
My mom was talking with her at church the other day.  I guess she isn't 
really plugged into any fellowship group at State.  My mom thought that you 
could invite her to Navs or something.  Anyhow,

Her info:
Beth Schwartz: 355-9392
She lives in Snyder Hall.


Love,
K
