I know of an instance several years ago where the computer dropped an entire preference party of 50 girls-panhell. would not allow those girls to be invited back (the chapter was prepared to call every girl before the preference party to let them know they had not been dropped)
panhell did nothing to help. So the girls thought the chapter had dropped them but it did not. It makes me so mad just thinking about it.
Unfortunately, I know of several more instances-what has made me angry is panhell would not do anything to help out and they would not rectify the situation. I can now see how a PNM can be accidentally dropped-especially in the large/competetive rushes. It is so sad that some of these PNM's blame themselves when it wasn't anything they did but a stupid computer glitch.
