I have met 2 sisters on this site (cash78mere and AlphaChi Girl) and we've been emailing and such. I think its great! I've also gotten contacts from them for other sisters which is great. We've discussed rush and other chapter business so its been really cool for me! I think, when used properly, that this site is really great for meeting sisters and brothers that can really share advice and past experiences, even if its not the same org. to which you belong!
One warning I want to throw out to everyone though: a few years back in undergrad school we had a girl on our hall who met some friends online. After graduation she turned up missing and the prevailing thought was she had run away. Well, sadly, in the winter when the leaves and such were all gone, a hunter found her body in the woods. She had mentioned online to a "friend" that she would email more later because she had to go for her daily run (this was early morning) and he apparently hacked info from the computer and found her during her run one day. Please be SO CAREFUL what info you are giving to people. This isn't one of those stupid emails I receive, if you want more info about the case as proof, you may email me. I just don't want to see on the news that one of us has been deceived with tragic results.
