's bloggers have posted comments from readers who want to pitch in tech skills and gear to help with the
Katrina nightmare. Someone even suggested turning the Superdome into a massive Internet "cafe." The lack of electricity has created a communications meltdown, cell phones being useless
without service or a way to

Community tech tools involved include the sobering Lost and Found section of
New Orleans's Craigslist. Those who can are snapping digital pictures and posting them to photo-sharing Web sites such as
Flickr. A
Katrina wiki has sprung up, but so have
scam donation Web sites.
