[stylist] creative writing web site question

[Vejas]

 Hi,
I was wondering if anyone has heard of a creative writing website 
calledwww.750words.com One of my friends told me about it today 
in creative writing club.  It's supposed to be a site where you 
can actually do your own private writing, or share if you want 
to.  However, I'm a little skeptical of using the site for my own 
private writing because the one person who is in charge of it 
stated that there would be some personal things he will find out 
(such as your location using google.)
So my 2 questions are: Has anyone heard of the site and used it? 
And, if you haven't heard of the site, what should you watch out 
for in finding a good creative writing site?
Thanks.
