I guess I'll go ahead and comment here along with ya'll
I'm a lil sis to a fraternity (won't way who) and a Sweetheart (duh

) to another. I have 2 lil bro's through my sorority's Lil Bro program and I love 'em!
Now, here at Rio lil bro/sis organization are a pretty big thing. Strange thing is, is that rush for lil's has a bigger turnout than our official rush for members.

I know that my sorority has had active Lil Bros since 1984 and have had no real trouble with them. I don't know if it's just here or anything but I know the sororities have had MUCH less trouble with our auxiallary groups than the fraternities.
Oh, just a side note, GLO's here do allow their lil bro/sis members to wear letters. However, each group has their own rules concerning it. (As in, with us we only let our guys wear the letters w/"lil bro" underneath them, or some groups only let them wear the letters in certain colors, etc)
