FYI, it is called either Discussions or Community Feed; so that it doesn't get confused with this type of forum.

For the Guidelines, see Help:Admin_and_Moderator_Tools_in_Discussions. I believe the welcome message is simply your wiki's mobile main page description. You can read Help:Mobile_Main_Page for information on how to change it. However, I don't think it is possible to have separate messages for Discusssions and the mobile main page; so changing it for Discussions will also change it for the mobile main page and vice versa.
