Lee Chin Wai blogged in Giving Back to Society about SG Gives, a portal for the public to donate to charitable causes in Singapore. I felt this is a worthy cause to promote. So, I'm lending support by adding this link at my blog as well.
According to the SG Gives website, it started in 2010 as an initiative of the National Volunteer & Philanthropy Centre (itself a non-profit organisation) to facilitate the improvement in quality and quantity of giving through a low cost, high reach tool for charities (excluding religious bodies) to raise funds.
For a tax savings perspectives, you may want to read Giving from the Heart - 80 Good Deeds as well.
