The JewishGen website is currently missing links to the individual
Sigs, and Donations to Sigs are not available under the DONATE button.
To get to the Bessarabia Sig website, I used Google and entered,
"Bessarabia Sig". Through the sig website, there is a tab to donate to
sig projects. I assume this will work for other Sigs you may have
joined until the website is fixed.
