There is a yahoo group for Cascadians at groups.yahoo.com/group/CascadeSurvivors, but I have to warn you all that there are a lot of people who loved the school on there who will blow sunshine up the ass of cascade haters or even up the asses of people who just didn't have a great experience.
So what I did was make a new forum for EVERYONE from Cascade - I made places on the forum for the cascade lovers, AND places for the Cascade haters. So come over to the new forum at cascadesurvivors.com - we talk about more than just cascade there also. I just started, so there is only 63 people signed up so far. The yahell group is 480+. I do moderate it a little, mainly just making sure the hate is kept in the hate forum and the love is kept in the love forum, for example.
Movie person, you can post your request for material there too, just please use your actual name like all the other grads so people know who you are.
Please, no cedu kids. It's not that I don't love you all too, but the forums are for cascade kids only.
