if you ban an user, you can send him a ban message as well. go to his or her profile and click on "ban profile". then a field will be opened, where you can write a message "you were banned for reason xy" and click on "lock user". the member will be shifted in a usergroup for banned users (it's the group "guests" but you also can create a new group for them). you can also decide, which rights the users in this group have (go to admin -> users -> usergroups and click on the group to edit the rights).

To unban the user, click on "reactivate user" (on his or her profile).
