Hi Everybody,

Our web site O Negative has undergone some major upgrades.
We moved to more reliable, faster and secure web server located in Europe.
That allowed us to upgrade the web site software and implement some useful features.
Now we have easy to use and stylish interface for mobile devises.
Some bugs are fixed, and some new plugins are installed.
We are also working on a system that locates and shows every member on a Google Maps.
When you open (in a non mobile devise) the member directory, you’ll see a map which shows the location (as avatar pin) of every member of our community.
We hope that this makes it very easy to find donor in your area.
For now the map is not optimized and not filled with all the members.
Soon we will make it to appear bigger and on a separate page.

Now members have the ability to send private message not only to friends, but to any member who covers the criteria for donors.

We will not stop here.
O Negative Web Site will keep on implementing solution and features for better connection between its members, and for faster response in urgent situations.

Do you have an idea for improving our web site?
Please share your thoughts.

The researches of R. Frank, a scholar at the University of Iowa, suggest that the Basques were far-advanced in navigational skills and other aspects of technology long before the rise of the Roman Empire. The Basques, she believes, are the last remnants of the megalith builders, who left behind dolmens, standing stones, and other rock structures all across Europe and perhaps even in eastern North America.

Two facts set the Basque peoples apart from the other Europeans who have dominated the continent the past 3,000 years: (1) The Basque language is distinctly different; and (2) The Basques have the highest recorded level of Rh-negative blood (roughly twice that of most Europeans), as well as substantially lower levels of Type B blood and a higher incidence of Type O blood.
