Minus is an online photo gallery type-thing. I had a lot of trouble understanding what I was supposed to do, but I figured out that you can add pictures and give them descriptions, then apparently you can save it and other people can see it, or something like that. I did not see a "Finish", "Submit", or "Done" button, and thus am forced to assume that by saving (which at the time I took to only save your work), other people are able to see what you made. You cannot edit the pictures, and there seems very little to do on the site. But I still got someone to follow me! And all I did was add like 7 cat pictures.
