I created a separate group to attract new members, rather than the existing Nsider fanartists. I wanted to convey the idea that you don't necessarily have to join Nsider2 to join in.
Of course, this is all in theory. If it rots like a bad apple this month, then we can move the contest to the Nsider2 group, and see what happens there. I figured creating a new group was low-risk, so I was willing to experiment with it.
If you have any ideas or comments, feel free to reply or contact me directly. I'm all ears.
