Awesome! Google Groups UI has been completed changed.

[Seabook]

Bit of lazy these days and didn't get into the Groups till today I found some interesting and useful sites which I want to share with you guys.

However, which impresses me is the whole UI of the Group has been changed into a new level, which is consistent to the Google+ and Gmail. Anyway, it's good to see the new UI.
But one pity thing is I still don't know how to modify the existing posts.

Anyone knows this, please kindly let me know.

Thanks,
Seabook
