Answer: the answer I would suggest is: .a telephone
.a computer
.tablets or I pads
.camera
Explanation: the multimedia media that I would suggest is, a Telephone, this can help one to post the same task that you posted, where one takes a photo then scan it to become even more visible and clear, it can also help one to see what the others posted.
.the other I would state is, computer because to is able, to post the task cause it is able to take photos too, and even one may use it to send the captured task from the phone for example, and ten can it too.
.Tablets and I pad because too there electronic devices which do the same works like the one computer does as the same the phone.
.cameras are also able to take the photos and te able to send them to another media that can modify them and then transfer them to any media they prefer.
