Interesting concept. Have they considered making it a bit more medium-size friendly, and marketing it to schools? School software tends to be waaaay behind what's even "good".
edit: after poking around a bit, I agree with x0t. It's a bit rough around the edges. But the simplicity is definitely a bonus (though I'd love the ability for a non-verified account to at least see the settings for groups, so you can at least see what you can do).
edit2: after verifying, the options are:
change name
"reset code" (regenerates your link)
notify everyone on post - on/off
delete group
Which pretty much sums up everything you can do with a group. It's just a bucket for members. Not sure what you can do aside from adding members and using a wall, haven't added myself w/ a second email and don't care to.
