Charity and service organizations are hoping people will remember Thanksgiving through all of the shopping days that followed.  With recent days of the holiday weekend dubbed Black Friday, Small Business Saturday and Cyber Monday, they're hoping Giving Tuesday will catch on more widely.  The global day is dedicated to giving back to communities and to celebrate generosity.  The Regional YMCA of Western Connecticut is among the organizations hoping for a bump to their bottom line through donations on Giving Tuesday.  They focus on youth development, healthy living and social responsibility.
