I think the new British site, Every Many Remembered is amazing.  It is of course, not only for “men” and is a combination of two sites – Every Man Remembered and Every Woman Remembered.  Go to http://www.everymanremembered.org/ and remember the fallen.

The site is a collaborative effort between the Royal British Legion and the Commonwealth War Graves Commission. They are inviting people to commemorate the fallen by finding a relative in the database of 1,117,077 men and women who died during the First World War, or by finding someone that no one has yet claimed, and writing a tribute. 

I am a firm believer of connecting to people from the past by somehow remembering their names, especially when the person may very well have no living relatives.
