How do you join a group in roblox

Scroll near down the bottom of the page, there will be a button that says "Join Group".


You may not be able to join a group because it may be Builder's Club only or Request to Join (private). Free members can join up to 5 groups, Builder's Club members can join up to 10, Turbo Builder's Club members can join up to 20, and Outrageous Builder's Club members can join up to 100.
