This is pretty important, sadly, especially within the Down syndrome community. There are a lot of trolls out there. We have this site as safe as we can make it, but you can help by watermarking the photos that you upload with your name. I recommend watermarking them in an area that is not easy to crop out.
Some tutorials for watermarking:
1. On the iPhone:
2. Using Google Picasa
3. Using PicMonkey
4. Using LightRoom
