zoo3700 on "Adding 100 authors?"

Hi,

I am currently teaching a University biology course that has about 100 students . I would like each of the students to contribute to a class blog about some of the invertebrates found in the area.

I am not sure of the best way to add them as authors- should I send them each an invite ? (seems kind of a tedious process), is there another way? I would like them to be able to upload photos etc.

Thanks for any help you can provide!
