Quite some time ago, I found a really cool and effective charity website called Tab for a Cause. I decided to tell you guys about it so hopefully, some of you sign up for it. Here's how it works.
Basically, every time you open up a new tab, the sites sponsors (the ads you see on the homepage) provide money that they give to a charity of your choosing. It's completely free, and you don't have to pay a cent for it to work. Also, the charities that they picked are really good. If you look at charitynavigator.org, you'll see that the charities that they chose are all top notch.
To sign up, visit this link: http://tab.gladly.io/?r=11146225
If you have any more questions about the site, ask me, and I'll do my best to answer them.
