sorry,i think i agree with I,brian here. even if you're not doing it for money, just for a hobby, or because you believe in the project, you need to make it look proffessional if you're appealing to wrtiers beyond your circle of friends.
i mean, the website doesn't give any information. where will the book be published(how?) where will it be onsale? why should i give them my story, just to be in a book, when i could send it to a magazine, have a small payment (even 5 bux) and know that it will at least be sold online, or to these shops, or whatever. and by at least having a decent website, with some information on it, i will know that the publisher is taking it seriously. that they will do things with my story, that i haven't just wasted it. after all, if i wanted to get that story printed again, it would be considered a reprint, so the market would be limited.
i agree, there is no harm in offering the opportunity to be in print, and it's good that you're supporting your friends, i just think that if the website had more info and was more proffessional looking, it would look more reliable and peopel would be more inclined to send their work in.
i mean, my friend gathered stories for an anthology he wanted to do. i would have happily given him a story for free (if i had one that fitted) because he was a friend, and i believed in his project. but he also had a proper website, a community on lj, that sort of thing, to promote and encourage it. he took it seriously, and just having a website that doesn't look proffessional makes it look as though they're not serious.
