In regards to the member Update Notifications page:
This page would be more useful if it had a link to the site instead of just the URL. If you 'target="_blank"' the link most browsers will not send the referer data, so it won't affect their stats. I would prefer if the link were simply an icon next to the domain name, NOT the domain name.
Maybe have *another* link (via icon) that goes to the WPMUDEV Dashboard (/wp-admin/network/admin.php?page=wpmudev) for each site as well.
It would also be nice if there was a way to permanently remove a domain from the list. I have a couple on there for sites that simply don't exist anymore - and while it's nice I can "disable" updates for them, I would just as soon remove them entirely.
