urgent help needed

Help
I’ve got latest version of wordpress with new buddypress for single install. Want to add blog to each group. The Groupblog plugin says its for mu installs – how do i modify it to work in my situtation? Also how do i get it so that the group blog allows a conversation between the group members and is singular to that group, so that is someone posts in opne group it won’t show up in their other groups?
I’m a beginner and reallly need urgent help with this as its for work :/
