I don't know if this one has already been posted but I've seen moonfruit websites for certain sororities. They are free, easy to use and generally appealing to the eye. I've seen a lot of DePaul sororities use moonfruit.
Where I go to school, only one sorority has a website. However, I think it's probably something that my sorority and the other two should look into. After all, life has become so based on technology!
