Just an idea I just thought of.
If a Jr member fails to be an active participant. You can request a poll to decide if the user stays on the team. A poll only other Jr GFX members can vote on.
Also, any changes you want made that deal with the Jr Graphics team can be handled in a similar fashion. The only regulation would be that you need ask a gfx team member before calling the vote. As to prevent unreasonable changes.
What do you think Jr Team?
