Move the student-facing features of group membership from Site Info to Roster.
PROBLEM TO SOLVE
The "Site Info" tool can be confusing to site managers (instructors, maintain users) since the name does not align to its function. In order to rename the "Site Info" tool to "Settings," select features of "Site Info" need to be moved to other tools. One of these functions is the ability for students to see group membership (already provided in Roster) and to join joinable groups. This latter item (joining groups) needs to be migrated to another tool, and Roster seems like the ideal fit.
Please provide a mechanism for students to join groups in Roster. Essentially, migrate the functionality that exists in Site Info to Roster and provide the appropriate button or option within the "Groups" drop down menu for a student to see joinable groups and join / leave groups.
