Kevin Lawrence Hanit - I have set two up for Lithuania (Lithuanian Massacres) and Ukraine (Holocaust in Ukraine). You can take a look at that format which would work for Belarus.
I do not like "Holocaust by Bullets", any more than I would have liked "Holocaust by Gas". Flippant book titles meant to generate sales do not reflect the seriousness of our purposes. If we would like to call a spade a spade, call it "Mass Murder in the Soviet Republics by Nazi Einsatzgruppen and their Local Collaborators", which would include 600 of my relatives killed in our ancestral town of Logoysk, Belarus, whom I will add as soon as I can figure out the crazy Geni search engine for adding profiles to Geni projects.
Adam - I was not able to add a public profile to a project today because I don't collaborate with the sole manager. As long as you are the manager of the profile, or collaborate with the manager, and the profile is public, you can add to a project once you join the project. There are three ways to do it:
Easiest is from Actions drop down on profile. Choose Add to Project and there will be a drop down of the projects you have joined. Or on the middle right hand side of the profle there is an Add to Project link, assuming that it's the first project you're adding the profile to. Or, alternatively, "follow" the profile and go to the project you want to add it to and from the Actions for the Project, on the drop down, choose Add Profile and type in the last name or the first if it's fairly unique and click on the correct choice if there are several.
