I have made a customized EMERGENCY type search engine that links only to crisis situation type websites (like relief aide, evacuation planning layouts, crisis management setup and others relating to disasters caused by terrorism, natural disasters, poverty, disease and man-made war), see  http://www.CrisisSearch.com ... This niche portal was made after the Katrina devastation (NOW THEY HAVE TO WORRY ABOUT HURICANE RITA) and hopefully it will assist humanity in/during the next disasterous crisis...

Please add related crisis blogs and websites to the database, already 1,000 websites spidered for meta data (fetched meta tags for description, title and keywords, plus we then grab the text from page and cache it for further searchable data)...

Also a portal as at the bottom of every search page has external links. Also a 'Suggestion Bot' that tries to suggest similar terms to use in further queries... Blogs/forums are on the way (being created so people can find more personalized one-on-one advice/help) for people to post missing friends, family, pets or post about volunteering or possible stradegies for Emergency Planning for current crisises or Clean-Up plans for past disasters.

My first ever nonprofit humanitarian project was  http://www.SpareSomeChange.com which only covers resources for those living homeless (I had suffered homelessness a few times as a youth). I will try to come up with other helping humanity type portals as I can afford too...
