We have just built Ultimategiftlists.com
My girlfriend keeps asking me what I want for Christmas. I also need to buy stuff for my nephew. So I wrote a list of stuff out for my girlfriend and sent her an email of links showing her the stuff I wanted. I found that my brother did exactly the same to show me what I should get my nephews.
There had to be a better way to do this. Amazon wishlist exists but it doesn't do it as effectively as I wanted. Therefore my mate and I built our new site - www.ultimategiftlists.com - it's hopefully very simple to use and has a really cool feature called 'giftmark' which enables you to add items to your list on the move. We originally built it just for us, to solve the problem I describe above. But, we figured it could be useful to other people.
We'd love any feedback you may have. Thanks in advance for looking at it.
