Can i block a message from a grou or the entire group for a day?

Question

a message that shouldn't have been written on the group was posted. how can i prevent members from viewing it? i have deleted, but nothing has changed..:|

Answer 1

deleting a post off the group just takes it off the group, anyone getting posts still get it-

consider moderating posts, which prevents these things

Answer 2

Deleting the message in your Group's archives should prevent anyone from viewing it on the Group's web site.  Though this would do nothing about members who received it in their e-mail because they're set to Individual Emails; and there's nothing you can do about these e-mails.
