That's a great question and it's good to see posts in here on things we can all agree, although terrible it had to be under such circumstances.  RWS set up a link where you can all donate if you wish through the International Red Cross.  It's been mostly RWS employees using this but it is open to everyone who is looking for a way to support the people of Ukraine to help ensure they have essential supplies, food, water as well as providing aid to hospitals and families.

Thank you for informing us of the way we donate to Ukrainians through RWS frame. I sincerely hope that Ukrainians have their happy daily lives again as soon as possible.
