problems with another sorority

[AlethiaSi]

i'm currently in london- but i've been talking to my girls back at home about rush... another sorority that is national has been saying really nasty things about us to pnms... that we're dying off- that we are ugly and fat- etc etc etc... (we used to have a bad stereotype- but now we're all really pretty- love to go out- and recruited 16 girls last spring- myself included and now we have 25) this other sorority has about 40 girls- and their rep is going down as being kinda boring (i go to a smaller school- about 6000 with a smaller greek community) but we have a lot of friends in other sororities and we don't ever say anything bad abotu other sororities at all... well this past fall... we had problems with this sorority- the things i mentioned above- we reported them but nothing much happened.... so this semester with formal rush- they deliberately made up lies about us and told pnms- (they were friends of ours that were rushing) and said that we were dying off- fat- ugly- etc etc... and that we sent hate letters to this girl- we don't even know who this girl is!!! its rediculous- and they brought up one of my sisters on charges of harrassment... when she did absolutely nothing- had never spoken a word to this girl in her life.. it just doesn't make any sense... i know you are probably thinking athat something is missing- but its not! they have deliberately been attacking us since we started getting bigger- we are going to go to the greek standards board i believe... but what else can we do- has this happened to anyone else??? i don't even know what to say to my friends that are in the otehr sorority.... its embarrassign and childish not to mention rediculous... any thoughts or ideas?? thanks
