I think the first thing that needs to be done is to assign 1 or 2 people for each different part of the process.

~ poetry~art~photography~stories~computer based imagery and so on.....

I think the poetry part is covered as basically the whole poetry community has already posted here.
Jobe looks like he can handle photography and related subjects, although he could still use a little help.
It would be cool if we could get people to volunteer for each part.

It's a pretty big thing and not as simple as it may seem.
Another good idea is what renovate suggested, which is to post threads in each forum so that people can start submitting work they feel most represents them here at DF. And one piece at a time folks, otherwise it's just gonna get too hectic.

And after that it's matter of deciding on the format of the actual book.
As Sire said, i'm sure the computer forum guys can help with said subject.

Anyways, keep ideas coming.....for it has only just begun.
