At the software company I work for, one of our engineers has a very sick little boy. His email to use was as follows:
"My family got bad news - doctors said allogenic bone marrow transplantation is the only chance for my son Ivan. 8 months of heavy and expensive immune suppression brought some positive results so we hoped that recovering is just question of time. Ivan is very brave boy - not every human meets so much suffering during whole life, like Ivan already met in his 2,5 years. But long road is still in front of us to get full recover - we are ready to come it through. Ukrainian clinics have no technical possibility to do such complex operation, so we need 150-250K EUR for Israel or European or US clinic. The final decision will be made considering amount we able to find. Perhaps my family is able to get ~60% of that by selling the flat where parents leave and some other goods, but we still require external help."
We have set up a donation site for Ivan that you can contribute to. Donations are coming in, but we're still short of the goal. If you can donate any amount, please visit http://www.mysql.com/about/help-ivan.html and do.
