NEMO has a private forum on cd (and we cannot thank cd enough for this service!)
I have the pleasure of "letting" mentors through the door (and keeping all the spambots out. Who the heck is "Dark Helmet" anyway and why are then spending so much time trying to sign up for NEMO

?)So I am on cd at least once a week to do that task.
I don't keep this page open, but probably do check in at least once a day, scanning the portal for topics of interest.
