I've recently discovered e-mint. It is a Yahoo! Group that discusses how to run online communities.
They are a friendly bunch, as shown by the warm welcome I received from Tamara Littleton of eModeration:
"We worked with a Mint Digital application on a very successful social network for ABC Family over at Disney [Virtual Rush], we love you guys :)
Not everyone puts as much care into the moderation tools. They're often an afterthought so it was good to work with people who thought about how moderators would use the tools."
It's reassuring to see that e-mint possesses the very features of online friendliness that it exists to promote.
