wordpress news

Hello WPMU DEV,

Please how do I remove the wordpress news that shows in the new blogs user dashboards?

I desire to remove or replace the Wordpress Blog section and the Other Wordpress News section. Also, is there a way for me to auto replace all the Hello World first posts in the newly created blogs or do I have to manually edit all the themes "Hello World" posts?

Please guide me.
Thanks.

Bro Louis.
