Useful places to look when planning a RTW trip

I will try to edit this as I find new sites.

Forums and Blogs:
http://www.ultimate-trip.com/
Has some nice videos (esp. Nepal) of places that he has traveled.

http://www.travelpod.com/
The best of everything. Blogs, forums and general info.

http://www.thirteenmonths.com/index.htm
An interesting blog detailing a couple's travels around the world. It's a nice balance to the standard backpacker blog in that they did not try to do it on the super cheap.

http://thorntree.lonelyplanet.com/
Lonley Planet's forums. Great practical information and a good place to ask questions. Warning: Like most forums it has developed its own culture. If you are a "newbie" expect the usual forum-types screeching at you to "search the forum,idiot" "try google," etc. Don't be deterred. Keep reading and posting.

How to sites:
Packing and Gear ideas:
http://www.onebag.com/list.html
Wonderful down-to earth advice on traveling. I have used his packing list as my guide in my planning.

Tour Sites:
http://www.travelchinaguide.com/
I can't vouch for the tours themselves, this site is great for getting a sense of China's scale and what is possible to see in X number of days.

http://www.seat61.com/Trans-Siberian.htm
Much like above, only for taking the trans-Mongolian or Trans-Siberian rail.

General Info Sites:
http://travelindependent.info/
Great for getting a sketch of countries. I've used it as a jumping off point for researching possible destinations. The site is also a solid clearinghouse of information from immunizations to what-to-pack lists. Check out the photography as well.

Lodging:
http://www.usservas.org/traveler.html
An interesting alternative to the hostel/tourist method. The organization works as a host-family setup with the overarching goal of cultural exchange and encouraging peace.

Healthcare:
http://www.fitfortravel.nhs.uk/
Scotland's NHS site for travelers. Sure I'm not Scottish, but the site is really handy for malaria maps, advice, etc.
